API Degree To Specific Gravity Calculation

pinit fg en rect gray 20 API Degree To Specific Gravity Calculation

This is not brand new formula but very handy calculation to have. The importent calculation for Petroleum Engineer.

API Gravity = ( 141.5 / Specific Gravity ) – 131.5

Specific Gravity = 141.5 / ( 131.5 + API )

Example: pure water at 60 deg F with  a specific gravity of 1.0 would have an API gravity:

API Gravity = ( 141.5 / 1.0 ) – 131.5 = 10 deg API
