Ideal Gas Pressure

p = n R T / V

How to Use This Calculator

Enter quantity of gas (mol), temperature in kelvin, and volume in cubic meters. Click Calculate to get pressure.

Formula

p = n R T / V

Applies for ideal gases at moderate conditions. For high pressure or low temperature, real gas models are needed.

Frequently Asked Questions

Can I input mass instead of moles?

Convert mass to moles using n = mass / molar mass, then use this calculator.
