[USMA 316] Re: Units mixup

The last paragraph is troubling.  The same group has "used the wrong gas constant" before.  This seems like it is the kind of mistake you wish to be careful to not repeat.  However, it is also a consequence of using "naked numbers."  If you do calculations without the units appended to your

Respectfully disagree, and I earlier posited that it was energy per unit length of the bolt.  In electrical and magnetic fields, line sources are frequently assumed as an approximation.  Of course, real sources would tend to have a diameter, but for distances large compared to diameter, but

It might be the energy dissipated in air by the arc.  Once the arc is struck, the voltage drop (per meter) is relatively low, MUCH less than the initial brekdown voltage. From: Stanislav Jakuba To: U.S. Metric Association Sent: Wednesday,

[USMA 261] Re: Is this covered by the FPLA?

I think the answer is yes.  The text of the FPLA (and FTC regulations) is given on the metric laws page of the USMA website.  Whats covered is in section 1459 of the FPLA. If it is not covered by the FPLA, it would fall under UPLR.  Unfortunately UPLR is only model regulations.  Many states

[USMA 260] Re: How common are kitchen scales?

I bought mine online but B stores like Williams Sonoma, Sur La Table definitely carry them.  Also plenty of articles about professional chefs using weight, but MOST American recipes are volume-based and many people don't see the need.  If you wanted one, there is no problem finding a large

[USMA 255] Re: How common are kitchen scales?

The simple answer is "have a scale." But for those who enjoy mind-numbing conversions, you could look up the nominal weight (and range?) for each grade of egg, the nominal densities of flour and sugar, and convert it all to volumetric.  You'd have a few recipes, depending on what size egg you

[USMA 235] Re: How common are kitchen scales?

In the US, I would say relatively rare.  It would almost require some special interest, portion control for diabetes or weigh loss, interest in cooking "foreign" recipes, etc.  If the household has one, it is likely to be a spring type, and moderate capacity to determine cooking times for large

Martin, The TTB (responsible agency) had proposed a unit of alcohol equal to 0.5 US fl oz (computed from % alcohol by volume).  If you allow for minor rounding, about 15 mL or 12 g of pure ethanol.  It never was officially approved but seems to have some informal use treating the 3 possible

I was actually expecting that Canadians get metric instructions and was wondering why they couldn't be made available here.However, since Imperial gallons have 160 fl oz, not 128, the mixing directions would have to be different in Imperial (1.875 Imp fl oz per Imp gallon) From: Martin

In the Preface to the SI Brochure, the BIPM notes that THEY use the point as the decimal marker in the English text and the comma in the French text (the only two languages they support). I think the logical conclusion is that the English language and English-speaking countries use the point,

Lengthy discussion on metric reddit.  The IAAF is now accepting mile qualifying times to run the 1500 m at world championship level, and USATF accepts them by appeal only for US Olympic Trials.  At most only the mile and 1500 m are affected. However, athletes feel running the mile is

I'm a little surprised the Feds only require 2.84 oz in a 5 oz can (56.8%).  This strikes me as a product that should be sold by drained weight as nobody uses that water.  In Canada, it IS.  A little Googling shows that Safeway Canada sells a roughly 6 oz can, labeled 170 g net weight, 120 g

If it were water, 2 teaspoons would be close to 10 g.  However, coffee grinds have a much lower bulk density than water.  Peet's is likely close on 2 T = 10 g.  However, the ratio also depends on how you brew the coffee (and personal preference).  Most people use drip machines, and that is way

Hi Pat,   We will probably remain on opposite sides of this issue, but a few thoughts:   On page 3, you assert Congress has never spoken on the spelling issues.  On other pages you recognize they did in the Metric Act of 1866.  That was obviously a long time ago.  However, I would assert they
