Thanks Pat.
The list I saw was about quantities and energy in various foods in the SI
and not global warming. It was a list of about 30 or so foods. Very neat
list without text.

About a year ago someone provided a long list of energy units for
quantities of food in SI rather than in calories.
Would you please send that list to me so I may recommend its use?

Dear Stan,
I published a list of 93 energy measuring words as part of my article, 'A
word about global warming' see:
http://www.metricationmatters.com/docs/AWordAboutGlobalWarming.pdf
My list included all of the various calories and Calories that I found
calibrated to different temperatures as the measurement of heat energy in food
is temperature dependent. British Thermal Units and Calories share this problem
Here is an extract:
When I searched for the ways people describe energy use, I quickly found lots
of different words that purport to describe amounts of energy. However, I doubt
that my searching did little more than scratch the surface. Here are 93 energy
names that I have collected so far:
Old pre-metric, early metric, and mongrel energy units
Atomic energy unit, barrel oil equivalent, Billion electron volts, British
thermal unit (0 °C), British thermal unit (16 °C), British thermal unit (20
°C), British thermal unit (32 °F), British thermal unit (4 °C), British thermal
unit (60 °F), British thermal unit (68 °F), British thermal unit
(international), British thermal unit (ISO), British thermal unit (IT), British
thermal unit (mean), British thermal unit (thermal), British thermal unit
(thermochemical), calorie, Calorie, calorie (16 °C), Calorie (16 °C), calorie
(20 °C), Calorie (20 °C), calorie (4 °C), Calorie (4 °C), calorie (diet
calorie), Calorie (diet kilocalorie), calorie (int.), Calorie (int.), calorie
(IT), calorie (International Steam Table), Calorie (it), Calorie (international
steam table) , calorie (mean), Calorie (mean), calorie (thermochemical),
Calorie (thermochemical), calorie (USA Customary), Calorie (USA Customary),
Celsius heat unit (int.), coulomb volt, cubic centimetre atmospheres, cubic
foot atmospheres, cubic meter atmospheres, dutys, dyne centimetres, electron
volt, erg, foot-grains, foot-pound force, foot-poundal, gigaelectronvolt, gram
calorie, gram calories (mean), hartree, horsepower hours, horsepower hours
(metric), inch pound force, Kayser, kilo, kilocalorie (16 °C), kilocalorie (16
°C), kilocalorie (20 °C), kilocalorie (4 °C), kilocalorie (4 °C), kilocalorie
(diet kilocalorie), kilocalorie (int.), kilocalorie (int.), kilocalorie (IT)
(International Steam Table) , kilocalorie (mean), kilocalorie (thermochemical),
kiloelectronvolt, kilogram calories (int.), kilogram force meter, kiloton TNT
equivalent, kilowatt hour, kilowatt minute, kilowatt second, megaelectronvolt,
megaton TNT equivalent, megawatt hours, newton meter, newton meters, Q unit,
quadrillion, quad, Rydberg, therm (EC), therm (US), thermie (16 °C), ton TNT
equivalent, tonne coal equivalent, tonne oil equivalent, watt hour.
I am aware, by the way, that some of these are actually equivalent to each
other. For example, I think that a Rydberg is equivalent to a Kayser, but I
doubt that this equivalence would be intuitive to many of our politicians.
But what is even more concerning is that when converting from one to another,
all these different energy words also require thousands of conversion factors
if energy issues are to be understood at even a basic level. The 93 measures
above require 8556 conversion factors to convert from any one measure to any
other.
Remember, in the International System of Units (SI) there is only one unit
for energy:
joule
Therefore conversion factors are not necessary — there aren't any.
The joule was first established as the international unit for heat and other
forms of energy in 1889. It is the only unit recognised for all forms of energy
in the International System of Units (SI) since then.
Since a joule is a relatively small amount of energy, it is usual to describe
larger amounts using the SI prefixes. Here is the complete list of those in use:
joules, kilojoules, megajoules, gigajoules, terajoules,
petajoules, exajoules, zettajoules, and yottajoules.
Given the nature of this linguistic problem how can we, as a nation or as a
world community, sensibly discuss energy issues when we don't know what other
people in other industries and in other nations are talking about?
