# Density of Water Calculator

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

1. First, measure the temperature of the water

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

2. Next, convert the temperature value

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

3. 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.
