Though these are not the SI units used for the Ideal Gas Law, they are the units most commonly used.

- Atmospheres (atm) or bars for pressure
- Liters (L) for volume
- Moles (mol) for n
- (L x atm)/(K x mol) or (L x bar)/(K x mol) for the constant
- Degrees Kelvin (K) for temperature

you should note that the values of R with both the pressure in atm and bar are given values on the constants sheet

R is the gas constant, 8.314 J / mol. K
