Ideal Gas Law

A calculator for the volume of ideal gases (ideal gas law). Please insert three values, the fourth will be calculated. You can choose which value you want to leave blank.

Formula: p V = n R T
R = molar gas constant = 0.08314472 (bar*L)/(mol*K)
L = Liter, K = kelvin

p pressure in bar:
V volume in L:
n amount of substance in mol:
T temperature in K:
