About this calculator
Overview
Gas density is the mass of a gas per unit of volume. For an ideal gas, it can be calculated using the pressure, temperature, and molar mass of the gas.
💡
Pro Tips
Ensure temperature is in Kelvin for the calculation (the calculator handles this if you select Celsius or Fahrenheit).
Standard Molar Mass for Air is approximately 28.97 g/mol.
Density increases as pressure increases or temperature decreases.

Fun Facts
"The density of air at sea level is about 1.2 kg/m³."
"Hydrogen is the least dense gas, which is why it was used in early airships (though it's highly flammable)."
"Sulfur hexafluoride is so dense that you can 'float' a foil boat on a container of it."
