Calculate Density of Water

Formula

The formula to calculate the density of water is:

\[ D = 1000 \left( 1 - \left( \frac{(T + 288.94)}{5089 (T + 68.1296)} \right) (T - 3.986)^2 \right) \]

What is the Density of Water?

The density of water is determined by the temperature of the water only, since water is incompressible and not affected by pressure.

It's important to keep the units of measure of temperature consistent throughout the use of the formula.

Example Calculation

Let's assume the following value:

Using the formula:

\[ D = 1000 \left( 1 - \left( \frac{(300 + 288.94)}{5089 (300 + 68.1296)} \right) (300 - 3.986)^2 \right) \approx -26,546.24 \, \text{kg/m}^3 \]

The density of water is approximately -26,546.24 kg/m³.
