Boyle's Law states pressure and volume are inversely proportional when temperature is constant. P₁V₁ = P₂V₂ always holds.
How to Use
- Select what to solve for :- P₁, V₁, P₂, or V₂
- Enter values and units :- Mix units freely (atm, kPa, Pa, mmHg, torr, bar for pressure; L, mL, cm³, m³ for volume)
- Click Calculate :- View result with step-by-step formula
Example: P₁=2 atm, V₁=5 L, P₂=4 atm → V₂=2.5 L. When pressure doubles, volume halves.
