Specific gravity (SG) for water is given for four different reference temperatures (4, 15, 15.6 and 20°C). From 0 to 100°C the pressure is 1 atm, and for temperatures >100°C, the pressure is equal to water saturation pressure .

Specific gravity measurement. The specific gravity is usually measured using an instrument called a hydrometer. The hydrometer partially submerges in the liquid sample, and the reading on the scale at the air-water junction point is recorded, as illustrated in Fig. 1.7.3.
Specific Gravity (Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as SG = ρ substance / ρ H2O (2)
An introduction to density, specific weight and specific gravity. Ethane Gas - Specific Heat vs. Temperature Specific heat of Ethane Gas - C2H6 - for temperatures ranging 250 - 900 K.
19 Ιουλ 2011 · Specific gravity is the density of the substance divided by the density of water, so `S.G.=\frac{Density\ ofobject}{Density\ of\ Water}=\frac{2.8\ \frac{g}{cm^{3}}}{1.0\ \frac{g}{cm^{3}}}=2.8` Note that the units cancel, so this answer has no units.
Specific gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature. The density of water at 4 0C is commonly used as a reference point.
Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F.
