Boyle's Law Calculator

Any pressure unit, as long as P₂ uses the same one. Leave at 0 if solving for it.
Any volume unit, as long as V₂ uses the same one. Leave at 0 if solving for it.
Leave at 0 if this is the value you are solving for — it is ignored.

Compressing a gas from 3 L to 2 L at constant temperature raises its pressure from 2 to 3 (in whatever pressure unit you started with).

P₁ × V₁ = P₂ × V₂ (constant temperature and amount of gas) · Powered by CalcHub — Boyle's Law Calculator
