How does this ideal gas law calculator work?

Initially affirmed by Émile Clapeyron in 1834 (as a combination of other two existing gas laws of Boyle, respectively Charles), the common form of the ideal gas law is P*V = N*R*T, while its molar expression is P*V = (m/M)*R*T. It is being used to approximate the behavior of various gases under specific conditions.

Where:

P = gas pressure

V = gas volume

T = gas temperature

R = the ideal gas constant equal to 8314.4621

m = mass

M = molar mass (please note that m/M represents the number of moles - N).

For each gas type from the drop down list, this ideal gas law calculator uses the molar masses from the periodic table of Mendeleev and requires three out of the 4 fields available (plus the gas name).

Depending on the given variables the following measurement units can be used at the data input within the form:

Pressure is by default set up to Pa but can be expressed using one of these units:

The temperature is by default in Kelvin but there are other two options: Celsius or Fahrenheit. The calculator will automatically convert it to Kelvin by using these conversion rules:

From °C to K = t°C + 273.15

From °F to K = (t°F + 459.67) * 5/9

Mass is in kg, while there are other 3 units available:
