[USMA 203] Unit mixup while surveying
A few weeks ago I went out with my new survey-quality GPS system to check coordinates of two benchmarks to make sure that I can use the system right. I went to a benchmark called Rainbow which was a bit hard to find. Not seeing it on the ground, I entered the coordinates and told the system to help me find it. It told me 4.6 meters of fill and a horizontal distance. I moved it around and found the benchmark, but was puzzled by this vertical discrepancy. I went to the other benchmark, named Oakland, which is easier to find, and got its coordinates. Again there was a 4.6 m vertical discrepancy. Yesterday I went to a job I've been surveying to get state plane coordinates. I noticed an icon on the data collector next to the number 6.562. I figured out that the icon means the pole height, and set it to the correct value, 2. Then I got coordinates of three points and returned home. It appears that I had a previous test job in feet, and the salesman had set the pole height to 6.562 ft, which is 2 m, and when I created my real job and set it to meters, the program took the number 6.562 and interpreted it as 6.562 m, resulting in the vertical error. I don't know why you'd want to enter the height of a pole used with a GPS unit in feet anyway, as fixed poles are used with GPS units, and they're always whole numbers of decimeters.

I've been ignoring the list because I've been busy with other things, such as surveying land.

I am now in Germany meeting someone I know from the Internet. Several days ago in my neck of the woods in North Carolina, the forecast was 95 mm of rain. I mentioned this to her; she told me about a recent flood in France which was some large number of liters per square meter. She did not know that a liter per square meter is a millimeter.

Back to the question. Suppose you're writing a program to keep track of fuel consumption and odometer readings of a car. Would you store the odometer readings -in whichever unit they are entered in? -always in kilometers? -always in meters? And the fuel consumption, would you store it in the unit it's entered in, in liters, or in cubic meters? Think of some other software that uses measurement and answer about it.

Another surveyor gave me some data from a topo he did so that I could test the program on data I didn't generate. I read the data in in feet and exported them in both feet and meters. (The native file format will have all lengths in meters, but it exports in feet or meters files which are loaded into data collectors.) The X and Y coordinates, which are all near 5 ft, came out as read in when written in feet, but the elevations, which are around 920 ft, came out ending with 0001 or . The reason is that the coordinates in meters are around 15200, which is slightly below 16384, but the elevations are around 280, which is a little bit above 256. The Sunday before last I profiled the program and found that it was spending the most time (not counting time spent in manysum, which had a long test routine) in area3, which computes the area of a triangle given the coordinates of its corners. For numerical stability (it's used also to tell how two line segments intersect), it sorts six products before adding them. I unrolled the sort loop and replaced it with a sorting network, which resulted in taking 1/3 as much time. A number of years ago I had to design a system that accepted logs of electrical data that was taken at various points around Italy. The data was collected at quarter-hour intervals, 24x7. The time system that I devised was to number the quarter hour starting 00:00 UTC on 1 Jan 2000 as interval 1, the quarter hour starting at 00:15 UTC on 1 Jan 2000 as interval 2 etc. All input data was converted to this format. A database table kept track of when the clocks went forward and when they went back, thus most days had 96 intervals, but one day a year had 100 intervals and another had 92 intervals. That's not an SI problem, that's keeping local time with summer/winter time changes. Pierre -- .i toljundi do .ibabo mi'afra tu'a do .ibabo damba do .ibabo do jinga .icu'u la ma'atman.
[USMA:54710] software that uses measurements
Other than astronomic (stars' masses are known more precisely in sun's masses than in kilograms), atomic (charges are integral numbers of elementary charges but unround numbers of coulombs), and angular (angles are often expressed as turns divided by an integer rather than radians), are there kinds of data that should be stored in non-metric units? Suppose you're writing a software program that handles measurements, and the data have been expressed in both metric and non-metric units. How do you handle input, storage, and output of data? I'm writing a surveying CAD program called Bezitopo. All data are stored in floating-point coherent SI units, except angles, which are stored in fixed-point 2^-31 turns, unless they're defining a position on the earth, in which case they will probably be stored as floating-point radians. Lengths can be input or output in meters, international feet, US survey feet, or Indian survey feet, but they are always stored in meters. LandXML has a tag that says what units measurements will be stored in. They can all be meters, or they can all be (US or international) feet. Pierre -- La sal en el mar es más que en la sangre.

This is in response to Sheri Porter's post on 2014-10-22, which I just found out about. I would like the American medical profession to adopt the metric system, and proper use thereof, as soon as possible. Two examples: When I visit the doctor, she measures my mass and temperature, among other things. This should be done in kilograms and degrees Celsius, which are the units I use at home and the units used all over the world. Measuring mass in kilograms and height in meters would facilitate the calculation of BMI, which is, and has always been, metric. I recently had my hormones measured. Free testosterone was quoted in picograms per milliliter, while total testosterone was quoted in nanograms per deciliter. Using different prefixes in both numerator and denominator makes them difficult to compare and constitutes abuse of the metric system. Proper style is to use a prefix in the denominator only if the resulting denominator is equivalent to a coherent unit (in particular, kilograms are used in denominators). Thus both figures should be quoted in nanograms per liter or, equivalently, in micrograms per kiloliter (since 1 kL=1m³). The common medical use of the deciliter in the denominator should be deprecated. Pierre Abbat -- .i toljundi do .ibabo mi'afra tu'a do .ibabo damba do .ibabo do jinga .icu'u la ma'atman.

Gram and meter were both borrowed from French, which, like English, forms plurals by adding -s (but it's usually silent), and which regularly stresses the last syllable of a phrase. Thus stressing kilometer, but not millimeter or kilogram or milligram, on the second syllable is not an explainable irregularity and should be avoided. Spanish does not have regular stress on nouns (it does on verbs, but it moves around, so some forms are always written with accents).

[USMA:52980] Metric system education
In a world where U.S. students are being left behind in important parts of the global job market, is nostalgia really a good guiding principle for education policy? Should we have kids walk two miles uphill both ways to school? The world is moving fast. There’s not much use for cursive writing anymore. Let’s let it go the way of instruction in the metric system. Huh??? I don't know whether cursive should be taught or not (I write both ways), but I do know that a major reason why U.S. students are left behind is that the school system insists on teaching, and much of the government insists on using, units that we gave up over 35 years ago. I live in Charlotte, 200 m from I-85. I grew up in California and Ohio, where I built things with 8 mm Lego blocks. I made partitions in a cupboard of a house I lived in (East Aurora, I think) with nine dowels spaced 50 mm apart. I have 75 g of rice, millet, and quinoa soaking in just over 75 ml of water. Around midnight, I mixed 15 g of henna, 7.5 g of amla, 7.5 g of cloves, and 90 g of water and applied it to my hair and nails (yes, I'm writing this with my head wrapped in plastic, as I do every month or two). I am 1.5 m tall and my mass is about 80 kg. I go at 60, 70, 90, or 100 km/h on the road, depending on which road it is. Don't ask me how many feet I am from the interstate or how many ounces of water the rice is soaking in. I don't know. I do know that 90 km/h=25 m/s. The metric system is designed to be easy to calculate in. A cubic decimeter is a liter; a liter of water is pretty close to a kilogram (which comes in handy when calculating how moist the soil is). A joule per second is a watt; a volt- ampere is also a watt. There are no incoherent units, such as cubic feet and gallons, in SI. Except for time and angle, where some units used with SI (not actual SI units) are in ratios of 60, and atom-sized units that most people don't need to know, every unit is 10 or 1000 times the next-smaller one. That's why it's used all over the world. If we want to get ahead in the global job market, we need to think in metric. To do that, we need to metricate the publicly visible measurements, such as road signs and weather, and stop teaching feet and pounds and miles and teach only metric.

What would a 3-D model of a metric cube, going from very small to very large look like? And would not other aspects of the cube (like length, water mass) also have a consistent, repeating pattern? I assume that SI units are infinite? Are all units interrelated or just some? According to the Fractal Foundation website: A fractal is a never-ending pattern. Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. Driven by recursion, fractals are images of dynamic systems - the pictures of Chaos. Geometrically, they exist in between our familiar dimensions. Fractal patterns are extremely familiar, since nature is full of fractals. For instance: trees, rivers, coastlines, mountains, clouds, seashells, hurricanes, etc. Abstract fractals - such as the Mandelbrot Set - can be generated by a computer calculating a simple equation over and over. I am not certain about this relationship but I consider it quite interesting to think about. If it were correct, it could change the conversation about metric units. A fractal is something whose Hausdorff dimension exceeds its topological dimension. You can have a coastline which is 100 km long if you measure it at the kilometer scale, 110 km long at the hectometer scale, 133.1 km long at the meter scale, and 177.1561 km at the millimeter scale. That's a fractal. The meter stick you measure it with is a straight line segment, not a fractal. If you measure a meter stick in micrometers, it is still a meter long. The fractality of the coastline when measured in the metric system is in the coastline, not in the metric system. Pierre -- lo ponse be lo mruli po'o cu ga'ezga roda lo ka dinko

I have an idea for the outer walls, it's a double wall configuration, instead of a 140 mm or 190 mm studs, two 90 mm studs alternating spaces from the inner wall and outer wall, so the two studs are never sided by side, in order to weave insulation between the studs. Studs are a heat sink in the walls, a bad thing. But you can still use a single 190 mm top and bottom plates. I'm building it of concrete blocks dry-stacked and filled with concrete. The actual length of a block is supposed to be 397 mm, but the actual spacing when laid is 400 mm. I got this both from a site that advocates the method (it gives the dimension in irches, which is quite unround, but converts to a nice round number in metric) and from someone who built like that and measured it for me. The wood parts are interior walls (one is load-bearing, the rest are just partitions), the staircase, and the roof and ceiling structure. Also I'm putting wood siding outside a 100 mm layer of insulation. The inside of the walls is not insulated; they're thermal mass. I'm probably going to use no drywall, but wood paneling, for the walls. I have to redesign the staircase. I originally assumed that the second floor would be 14 mm thick from the joists to the top, which have a rise of 203 mm for 15 rises, but it's more like 30 mm, so the rise is 204 mm, which means I have to lengthen the stairwell slightly to meet the headroom requirement. I have a query out to someone about the thickness of treads. I was using 38 mm softwood planks, but those will be only the temporary steps; permanent steps are hardwood, which is cut to different sizes.

At first sight, it appeared to me a very convenient form of land measurement, being about the area of two American football fields put together (easy to visualize), and convenient for measuring the size of most lots and estates. The other measurements, the square meter and square kilometer, seemed to produce numbers that were too large or too small, especially since Americans are used to evaluating the size of estates in terms of fractions of an acre, or tens or hundreds of acres (and very occasionally thousands and millions of acres). I prefer the dunam (el estrema, 1000 m²) to the hectare, because it agrees with the principle of powers of a thousand, and the hectare doesn't. But I much prefer the hectare to the acre. Sizes of countries significantly smaller than Egypt or Colombia (about 1 Mm² each) could be stated in megadunams. A square kilometer is 100 hectares, by the way.

I was at Whole Foods today (I'm visiting my aunt in Berkeley) and passed the olive oil. I saw a round liter can of oil, which I'm not used to seeing. The unit price on the shelf is in dollars per liter. Below it was a half-liter bottle, with the unit price in dollars per ounce. Huh?

[USMA:50942] unit symbols
I'm designing a solar house and found your site while searching for batteries for solar systems. I noticed such phrases as 1 Module for 12v systems and 90 lumens with a 200 ma draw. Could you fix these please? The proper way to write them is 12 V, 90 lm, and 200 mA. Units that are named for a person, such as the volt (for Alessandro Volta), have a capital letter in their symbol; units that are not, such as the lumen (from Latin for light) do not (except for the liter for typographic reasons). The symbol for hour is h (not hr), while H stands for the henry, the unit of electrical inductance. Also, I'd like to be able to view the site entirely in metric. All dimensions of my house are in millimeters, so I'd like to see the sizes of solar panels, stoves, and fridges in millimeters. Our officially preferred system of units is the metric system, and has been for decades. Metric is easier to calculate in. It's been my system since I played with 8 mm Lego blocks as a child, as well as that of many other Americans. Pierre -- La sal en el mar es más que en la sangre.
