Enter the temperature of the water into the density of water calculator. The calculator will display the water density.

## Density of Water Formula

The following formula is used to calculate the water density.

D = 1000 * {1 – [(T + 288.94) /5089* (T + 68.1296)] * (T – 3.986)^2}

- Where D is the density in kg/m^3
- and T is the temperature in Kelvin

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

How to calculate water density

**First, measure the temperature of the water**Using a temperature measurement device, measure the temperature of the water.

**Next, convert the temperature value**Since the formula used Kelvin as the units for temperature you need to convert the measure value to Kelvin.

**Calculate the water density**Calculate the water density using the temperature and formula above. You can also simply plug in the values to the calculator.

## FAQ

**What is water density?**

Water density is the total mass of water in a certain volume.

**Does pressure effect water density?**

Not in any significant way. That’s because typically water is considered an in compressible fluid.
