What is the Boyle’s Law Calculator?

The Boyle’s Law Calculator is a tool that helps you understand the inverse relationship between pressure and volume of a gas when temperature remains constant. According to Boyle’s Law, the product of pressure and volume stays the same before and after a change occurs. This calculator allows you to enter any three known values—initial pressure (P₁), initial volume (V₁), final pressure (P₂), or final volume (V₂)—and it automatically calculates the missing one. It makes solving gas behavior problems quick and accurate for students, teachers, and science learners.

How to Use:

1. Enter Initial Pressure (P₁): Type the starting pressure of the gas.
2. Enter Initial Volume (V₁): Input the initial gas volume.
3. Enter Final Pressure (P₂): Provide the final pressure if known, or leave it blank if you want it calculated.
4. Enter Final Volume (V₂): Type the final volume or leave it empty if this is the unknown value.
5. Click “Calculate”: The calculator will compute the missing variable using Boyle’s Law.
6. Review the Result: Use the displayed value for lab work, assignments, or physics/chemistry calculations. Make sure only one field is left blank for accurate results.
