The density of liquid water is nearly 1000 kg/m3. (1 gram/cubic centimeter)
The density of ice is 916.7 kg/m3 at 0 °C kg/m3.
Therefore ice floats in water.The SI unit for density is kilograms per cubic metre (kg/m3).
The density of fresh water is dependent on the temperature (and on any solutes):
At 3.98 degrees Celsius the density is 999.975 kilograms per cubic meter.
At 100 degrees Celsius the density is 958.35 kilograms per cubic meter.
