The density of water can be calculated by the following formula:
Density=mass/volume
Where, mass refers to the mass of water, in grams or kilograms, which can be obtained by weighing; Volume refers to the volume of water, in cubic centimeters, cubic meters, etc., which can be measured by the container.
At normal temperature and pressure, the density of water is about 1g/cm3 or 1000kg/m3. However, the density of water will change with the change of temperature and pressure, so corresponding correction is required under different conditions.
