How to Calculate PSI to Volume


V=P1×V1P2V = \frac{P1 \times V1}{P2}



Initial pressure (PSI)


Initial volume


Final pressure


Volume at final pressure

Example Calculation

  • Initial Pressure (P1): 100 PSI
  • Initial Volume (V1): 10 cubic feet
  • Final Pressure (P2): 50 PSI


V=100×1050=20 cubic feetV = \frac{100 \times 10}{50} = 20 \text{ cubic feet}

Initial PSI (P1) Final PSI (P2) Initial Volume (V1) Calculated Volume (V)
100 PSI 50 PSI 10 cubic feet 20 cubic feet
200 PSI 100 PSI 15 cubic feet 30 cubic feet


How accurate is the PSI to Volume Calculator?

The calculator provides an estimate. Actual values can vary based on temperature and gas type.

Can this calculator be used for different gases?

Yes, it can be used for any gas, but results may vary based on the specific properties of the gas.

Do I need to consider temperature changes?

For more accurate results, especially in the advanced calculator, consider temperature changes.

Final Thought

Hope, you found the PSI to volume calculator helpful for your projects. It is very useful tool for anyone working with gases. It can quickly calculate the volume at the new pressure. Don’t hesitate to ask any question I will be glade to answer you.
