Oxygen - Density and Specific Weight

Online calculator, figures and tables showing density and specific weight of oxygen, O2, at varying temperature and pressure - Imperial and SI Units

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