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.
