How to calculate pressure work
This calculator finds work done by a gas from pressure and volume change — a key thermodynamics calculation for expansion or compression processes.
How the calculation works
Work = Pressure × Volume change.
Example
A pressure of 200,000 Pa with a volume change of 0.002 m³: 200,000×0.002 = 400 J.

Pro Tips for Pressure Work
- This assumes constant pressure during the volume change (an isobaric process) — for a process where pressure varies, a more complex calculation (integrating over the pressure-volume curve) is needed.
- A positive volume change (expansion) means the gas does positive work on its surroundings; compression (negative volume change) means work is done on the gas.
Common Pressure Work Mistakes to Avoid
- Applying this constant-pressure formula to a process where pressure actually varies significantly during the volume change, where it would give an inaccurate result.
