Combined gas law is the combination of Charles’s law, Boyle’s law, and Gay-Lussac’s law. It states that the ratio between the pressure-volume product and temperature is a constant. In this calculator, the initial and final volume, pressure, temperature can be calculated alternatively with the other known values.

Formuls of Combined Gas Law
Gas Equation: PiVi/Ti = PfVf/Tf
- Vi = Initial Volume,
- Pi = Initial Pressure,
- Ti = Initial Temperature,
- Vf = Final Volume,
- Pf = Final Pressure,
- Tf = Final Temperature.
Example of Combined Gas Law
If the initial and final volume is 12, 2, initial and final pressure is 10, 7 and initial temperature is 5,
Tf = (Ti x PfVf) / PiVi
= (5 x 7 x 2) / (12 x 10)
Hence, final temperature is 0.58
