Ideal Gas Law Calculator
PV = nRT. Solve any unknown given the other three. Units: P in atm, V in L, n in mol, T in K. R = 0.08206 L·atm/(mol·K).
Results
P1.0000 atm
V22.4000 L
n0.9993 mol
T273.15 K
For non-ideal gases (high P, low T), use Van der Waals or compressibility factor Z. T must be in Kelvin (K = °C + 273.15).
