# Ethanol - Density and Specific Weight vs. Temperature and Pressure

## Online calculator, figures and tables showing density and specific weight of ethanol at temperatures ranging from -25 to 325 °C (-10 to 620 °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 [m 3 ] or [ft 3 ]

Specific weight , γ, has units typically [N/m 3 ] or [lb f /ft 3 ]  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/s 2 ] and value on Earth usually given as 9.80665 [m/s 2 ] or 32.17405 [ft/s 2 ]

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