The unit mole is short for gram molecule, in general, placing -mole, -ion, or -equiv, have the effect of stating N things, N electron-charges, or N valences (where N = avagadro's number = mass-unit / dalton). "Mole" itself is short for "gram-mole". The unit is thus a derived measure from mass, (ie number by weight), with a dimension M. There are indeed references to -mol as an addon to convert (mass) into (moles), eg lb-mol, (kgf-s²/m)-mol [used in the US standard atmosphere], and g-mole, kg-mole.
The SI system does not use the coherent unit (ie mass-unit / dalton), but either uses (gram/dalton) = gram-mole, or kg/kilo-dalton. Since there is plenty of reference to gram-mole, and few to kilo-dalton, one concludes that SI simply adopted established practice and uses the mole.
Since the former relation of (mole-unit) = (mass-unit)/dalton no longer applies, it needs then to be established that the (mole-unit) is no longer a derived measure but one that is independent of the weight. The sentence i wrote is indeed perfectly correct: moles were used with many systems but not as a base dimension, but it needs to be one in SI, because SI is not coherent there. -- Wendy.krieger ( talk) 07:21, 3 January 2012 (UTC)
It would be nice to have something about when FPS was invented, and when it came into general use. Zyxwv99 ( talk) 23:28, 18 January 2013 (UTC)
Hello fellow Wikipedians,
I have just added archive links to one external link on
Footâpoundâsecond system. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

System not in use no more said in link. [1]
It might be mostly not used in physics, but it is used in ChE. I don't know if there is a WikiProject for ChE, though. Gah4 ( talk) 19:40, 22 December 2021 (UTC) Note that it is also used in aeronautics, such as Thrust-specific fuel consumption. Not so long ago I was trying to figure out the source of some numbers, which came from the European version of the FAA. It seems that they converted the FPS values from the FAA to unusual metric units. (And to more significant digits than I could understand.) So, yes, it is in use, but mostly not in physics.
