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

## Online calculator, figures and tables showing density and specific weight of methanol,CH3OH, at varying temperature and 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 methanol 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 M ethanol Density Calculator

The calculator below can be used to estimate the density and specific weight of methanol at given temperature and atmospheric pressure. (Boiling point of methanol is -0.8°C / 30.5°F, and thus, methanol 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.
