Specific gravity (sp gr) measures the ratio of density of the substance to the density of water in a given temperature, (i.e., 4oC). It is a dimensionless unit. Oil gravity differs for each liquid. Use the online API to Specific gravity converter to find the Sp gr of an oil by providing the API gravity. API is measure of the density of a petroleum liquid when compared with the water.

If an oil has 26.5 deg of API, then its specific gravity is calculated as
s = 141.5 / ( 131.5 + 26.5 )
s = 0.8956
