* At 4°C (39.2°F) and 1 atmosphere of pressure: 1 gram per cubic centimeter (g/cm³) or 1 kilogram per liter (kg/L). This is the maximum density of water.
* At 20°C (68°F) and 1 atmosphere of pressure: 0.9982 g/cm³ or 0.9982 kg/L.
* At 25°C (77°F) and 1 atmosphere of pressure: 0.997 g/cm³ or 0.997 kg/L.
Important notes:
* Water density decreases as temperature increases.
* Water density increases with increasing pressure.
* The density of seawater is slightly higher than pure water due to the dissolved salts.
If you need the density of water at a specific temperature or pressure, you can find it in tables or use online calculators.
