Understanding This Calculator

Ideal Gas Law Formula

Relates pressure, volume, temperature, and amount of gas.

P × V = n × R × T

  • P: Pressure (Pa)
  • V: Volume (m³)
  • n: Moles
  • R: 8.314 J/(mol·K)
  • T: Temperature (K)

Example 1

n=1, T=273K, P=101325 Pa

  • V = nRT/P = (1×8.314×273)/101325 ≈ 0.0224 m³ (22.4 L)

How to Use

  • Enter three known values.
  • Leave one field empty or zero to calculate it.
