Propane - Density and Specific Weight vs. Temperature and Pressure

Online calculator, figures and tables showing density and specific weight of propane, C3H8, at temperatures ranging from -187 to 725 °C (-305 to 1300 °F) at atmospheric and higher pressure - Imperial and SI Units.

Density , ρ, has units typically [kg/m3] or [lb/ft3], and is defined by the ratio of the mass to the volume of a substance:

ρ = m/V                      [1]

where     m = mass, units typically [kg] or [lb]
V = volume, units typically [m3 ] or [ft3 ]

Specific weight , γ, has units typically [N/m3 ] or [lbf /ft3 ]  is defined by the ratio of the weight to the volume of a substance:

γ = (m * g)/V = ρ * g                [2]

where    g = acceleration due to gravity, units typically [m/s2] and value on Earth usually given as 9.80665 [m/s2] or 32.17405 [ft/s2]

Tabulated values of propane density and specific weight at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures.

Online Propane Density Calculator

The calculator below can be used to estimate the density and specific weight of propane at given temperature and atmospheric pressure. (Boiling point of propane is -42.2°C / -44°F, and thus, propane is present as liquid below this temperature)
The output density is given as kg/m3, lb/ft3, lb/gal(US liq) and sl/ft3 .  Specific weight is given as N/m3 and lbf / ft3.
