The Density of Water by Temperature calculator computes the density of water as a function of temperature, using the standard density of water (ρ) at standard temperature and pressure, and the unique temperature expansion coefficient of water.

INSTRUCTIONS: Choose units and enter the following:

• (T)  This is the temperature of the water.

Density of Water (ρ):  The calculator returns the density in kilograms per cubic meters.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the density of water based on temperature is:

ρ = ρ_(H_2O)/(1 + β(T - T_0)
