What the conversion for bar so that I can use it to work out volume and temprature? Whats the units?

1 bar = 100,000 pascals = 100,000 kg/m/s^{2}

Not to be a pain in the ***, but I'd normally think
kg/m/s^2 = kg s^2 / m But I guess it does come down to the conventional order of operations. I guess you win. Gack. I personally hate when people describe accelerations as "meters per second per second" i.e. m/s/s, for the same reason.  Warren

Interesting note:
In the "common" world, a bar has the unit "kg/cm^2". THis is referring to the weight of one kilogram per square centimeter. THis of course translates to only 98,010 N per square meter, but somewhere along the line, "g" got upgraded to 10 N/kg instead of 9.801 N/kg.

So what is it in hpdpcf's (horsepowerdecades per cubic furlong)?

1 bar is defined to be 100 kilopascals. A pascal is one newton per square meter. One kilogramforce is g newtons. Therefore, one pascal is (1/g) kilogramforce per square meter. Therefore, one bar is 100,000/g kilogramsforce per square meter. g is accepted to be 9.80665 m/s^2, so one bar is 10,197.1621298 kilogramsforce per square meter. I have no idea where you got the idea that someone rounded g to 10 m/s^2, but it never happened.  Warren

I used the Unix 'units' program, since I had a shell already open ...

So g was not the one that was adjusted. It's the bar that was raised.
