Boyle’s Law Calculator

Calculate final pressure or volume for an ideal gas at constant temperature using P₁V₁=P₂V₂.

These are ideal thermal/gas models. Real material properties and gases can vary with temperature, pressure and phase.

How to use

Boyle’s law links pressure and volume for a fixed amount of ideal gas at constant temperature. Solve P₂ or V₂ while keeping units consistent.

  1. Choose P₂ or V₂.
  2. Enter P₁ and V₁.
  3. Enter the other known final-state value.
  4. Keep units consistent.

How it is calculated

P₁V₁=P₂V₂

Example

Example: P₁=1, V₁=2 and P₂=2 gives V₂=1 in the same volume unit.

Important notes

Assumes constant temperature and gas amount with near-ideal behavior; real gases deviate especially at high pressure or near condensation.

Frequently asked questions

Must pressure be Pa?

No, any pressure unit works if consistent.

Can L and m³ be mixed?

Not without conversion.

If pressure doubles?

Volume halves at constant temperature in the ideal model.
