Ideal Gas Law Calculator

Calculate pressure, volume, moles, or temperature using PV = nRT

Enter any three values to calculate the fourth

Pressure (Pa):

Volume (m³):

Number of Moles (mol):

Temperature (K):

R = 8.314 J/(mol·K)

1 atm = 101,325 Pa, K = °C + 273.15

PV = nRT

Where: P = pressure, V = volume, n = moles, R = gas constant, T = temperature
