The units
- kg/m³ (kilograms per cubic metre): The SI unit of density.
- g/cm³ (grams per cubic centimetre): Materials data; water is about 1.0.
- g/L (grams per litre): Solutions and gases; numerically equal to kg/m³.
- lb/ft³ (pounds per cubic foot): US material and fluid density.
- lb/in³ (pounds per cubic inch): US metal and machined-part density.
- lb/gal (pounds per US gallon): US liquids and fuels.
- slug/ft³ (slugs per cubic foot): US fluid mechanics.
Water is about 1,000 kg/m³ (62.4 lb/ft³) near room temperature, and density changes with temperature and pressure, especially for gases.
