Ideal Gas Law Calculator

The equation of state of a hypothetical ideal gas (PV = nRT).

Calculated P
1.0007 atm

Σ The Formula

PV = nRT

Real World Examples

STP Condition
1 mole of gas at 273.15K and 1 atm occupies ~22.4 Liters.
Compression
Halving the volume at constant temperature doubles the pressure (Boyle's Law).

# About This Calculator

The Ideal Gas Law describes the behavior of gas particles under various conditions of pressure, volume, temperature, and amount of substance.

Variables:

  • P: Pressure (in atmospheres).
  • V: Volume (in liters).
  • n: Number of moles.
  • T: Temperature (in Kelvin).
  • R: Idea gas constant (0.08206 L⋅atm/mol⋅K).

How To Use

  1. Choose the variable you want to **Solve For**.
  2. Enter the values for the other three variables.
  3. Ensure temperature is in **Kelvin** (K = °C + 273.15).
  4. The result is updated instantly with the correct unit.

Frequently Asked Questions

What is an 'Ideal' gas?+

A gas where particles do not attract/repel each other and occupy zero volume. Real gases behave mostly like ideal gases at high temperatures and low pressures.
