Boyle's Law Calculator
Calculate final pressure using Boyle's law P₁V₁ = P₂V₂
About this calculator
The Boyle's Law Calculator helps you determine gas pressure or volume changes when temperature remains constant. Using the fundamental equation P₁V₁ = P₂V₂, this tool instantly calculates final pressure when you know initial conditions and final volume, or vice versa. It's essential for chemistry students, researchers, and professionals working with gas systems, scuba diving calculations, or industrial applications where gas behavior prediction is crucial.
How to use
Enter the initial pressure (P₁) and volume (V₁) of your gas sample. Input either the final pressure (P₂) or final volume (V₂) that you know. Click calculate to instantly find the missing variable using Boyle's Law equation.
Frequently asked questions
What is Boyle's Law?
Boyle's Law states that pressure and volume of a gas are inversely proportional at constant temperature, expressed as P₁V₁ = P₂V₂.
When does Boyle's Law apply?
Boyle's Law applies to ideal gases at constant temperature and with a fixed amount of gas in a closed system.
What units can I use?
Any consistent pressure units (atm, Pa, psi, mmHg) and volume units (L, mL, m³) work as long as matching units are used.
