Boyle's Law Calculator

Squeeze the volume, the pressure rises.

Pressure and volume move in opposite directions

At constant temperature, compressing a gas into a smaller volume forces its pressure up proportionally — P₁V₁ = P₂V₂ captures this inverse relationship exactly.

Everyday Boyle's Law

A syringe with the tip blocked, a bicycle pump, and the way your lungs work when you breathe all rely on this exact relationship between squeezed volume and rising pressure.

What you entered

Initial pressure (atm): 1Initial volume (L): 10Final volume (L): 5

P₂ = P₁V₁ ÷ V₂
(1 × 10) ÷ 5= 2

Result

Final pressure: 2 atm

Compressing to 5L raises the pressure to 2 atm.
