What the conversion for bar so that I can use it to work out volume and temprature? Whats the units?
Should be kg/m-s^{2}Originally posted by Ambitwistor
1 bar = 100,000 pascals = 100,000 kg/m/s^{2}
Uh.... no.Originally posted by Chi Meson
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.
1 bar = 3.4595574 hpdpcf'sSo what is it in hpdpcf's (horsepower-decades per cubic furlong)?
I see your Schwartz is as big as mine.Originally posted by Ambitwistor

$ units
2084 units, 71 prefixes, 32 nonlinear units
You have: bar
You want: horsepower-decade/furlong^3
* 3.4595574
/ 0.28905432
That's not what I meant, really. In Europe, the unit of bar and kg/cm^2 is used interchangeably (not by scientists, but by people pumping their bike tires). I remember several times over the years hearing anecdotaly that the bar was based on the "kg/cm^2" but was then redefined to be essentially 10 N/cm^2 (actually 1,000,000 dynes per cm^2)to be scientifically correct.Originally posted by chroot
Uh.... no.
1 bar is defined to be 100 kilopascals. A pascal is one newton per square meter. One kilogram-force is g newtons. Therefore, one pascal is (1/g) kilogram-force per square meter. Therefore, one bar is 100,000/g kilograms-force per square meter.
g is accepted to be 9.80665 m/s^2, so one bar is 10,197.1621298 kilograms-force 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.
