• ### Density, Specific Weight and Specific Gravity

It is common to use the density of water at 4 o C (39 o F) as a reference since water at this point has its highest density of 1000 kg/m 3 or 1.940 slugs/ft 3. Since Specific Gravity - SG - is dimensionless, it has the same value in the SI system and the imperial English system (BG).

• ### How to Calculate Density by Water Displacement | Sciencing

Water displacement uses a particular property of water: 1 milliliter (abbreviated ml) of water takes up 1 cubic centimeter (cm 3) of space, or volume, when the water is at standard temperature (0°C) and pressure (1 atmosphere). An object completely submerged in water displaces or offsets a volume of water equal to the volume of the object.

• ### What Is the Density of Water? By Temperature and Unit

Jul 04, 2018 · Density is mass divided by volume (ρ=m/v), and water was used as the basis for establishing the metric unit of mass, which means a cubic centimeter (1cm 3) of water weighs 1g. So, 1g/1cm 3 = 1 g/cm 3, giving water it's easy-to-remember density. However, water's exact density depends on both the air pressure and...
