Formel

V₁/T₁ = V₂/T₂ → V₂ = V₁ × T₂/T₁, where temperatures are in Kelvin. Input is in Celsius (converted automatically).

Häufig gestellte Fragen

What is Charles's law?
Charles's law states that the volume of an ideal gas is directly proportional to its absolute temperature at constant pressure.
Why Kelvin?
Gas laws use absolute temperature (Kelvin) because volume is proportional to absolute temperature, not Celsius.
