Specific gravity (SG) for water is given for four different reference temperatures (39.2, 59, 60 and 68☏).įrom 32 to 212☏ the pressure is 14.7 psi, and for temperatures >212☏, the pressure is equal to water saturation pressure. Specific gravity (SG) for water is given for four different reference temperatures (4, 15, 15.6 and 20☌).įrom 0 to 100☌ the pressure is 1 atm, and for temperatures >100☌, the pressure is equal to water saturation pressure.

Specific gravity of liquid water ranging 32 - 700 o F and 0 - 370 o C is given in figures and tables below: Specific Gravity - SG - is dimensionless and has the same value in the SI system and the Imperial English system (BG). The temperature and pressure must always be specified for both the sample and the reference. Pressure is nearly always 1 atm (101.325 kPa). For gases it is air at room temperature (25☌).

Water is normally also used as reference when calculating the specific gravity for solids. related to crude oils and petroleum products.

However, also the density at 60 ☏ (15.6☌) or 20 ☌ is often used as the reference temperature, e.g. It is most 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 sl/ft 3. Ρ substance = density of the fluid or substance Specific Gravity (= Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of a reference substance - at a specified temperature and pressure, and can be expressed as
