Nitrogen - Density and Specific Weight vs. Temperature and Pressure

Sponsored Links

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 nitrogen density at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures.

Online Nitrogen Density Calculator

The calculator below can be used to estimate the density and specific weight of gaseous nitrogen at given temperature and pressure.
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.
