### What Is the Density of Water? - ThoughtCo

The density of water is the weight of the water per its unit volume, which depends on the temperature of the water. The usual value used in calculations is 1 gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm 3). While you can round the density to 1 gram per milliliter, there are more precise values for you to use.
