Chemistry
Boyle's Law Calculator
Solve final pressure or final volume for a fixed amount of ideal gas at constant temperature.
Formula
Initial pressure x initial volume = final pressure x final volume.
About the Boyle's Law Calculator
Solve final pressure or final volume for a fixed amount of ideal gas at constant temperature.
How the Boyle's Law Calculator Works
The selected unknown is isolated from the constant pressure-volume product while all pressure values and both volumes remain in matching units.
Formula
Initial pressure x initial volume = final pressure x final volume.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
Temperature and gas amount must remain constant and the gas should behave approximately ideally. Use absolute pressure, not gauge pressure, for physical gas calculations.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
