# Specific Gravity Of Oil Calculator

Specific gravity (sp gr) measures the ratio of density of the substance to the density of water in a given temperature, (i.e., 4^{o}C). 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.

Code to add this calci to your website

#### Formula:

s = 141.5 / ( 131.5 + a )
**Where,**
s = Specific Gravity of Oil
a = Degree of API Gravity

#### Example

** 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
