## Quick Answer

Solve the ideal gas equation PV = nRT for pressure, volume, moles, or temperature. Input four variables to calculate the fifth.

## Definition

The ideal gas law is an equation of state that describes the behavior of a hypothetical ideal gas, written as PV = nRT, where P is pressure, V is volume, n is the amount of substance in moles, R is the gas constant, and T is temperature. An ideal gas law calculator solves for any of these variables when the other four are provided. It supports conversions across multiple units of measurement. Physicists, chemical engineers, and students use it to analyze thermodynamic systems and gas behavior.

## How to Use

1. **Select target variable** — Choose the gas property you want to calculate, such as pressure or temperature.
2. **Enter known gas properties** — Input the values for the other four variables, selecting the correct units for each.
3. **Review the result** — View the calculated value along with unit conversions and the formula breakdown.
