About API Gravity Calculator

Calculate the API Gravity from density or specific gravity or preloaded database

The API gravity or American Petroleum Institute gravity is a term often used to measure how heavy or light a petroleum liquid is comparing to water. This application allows you to perform any of the following operations:

+ Calculating the API gravity from Liquid density or specific gravity or preloaded database of fluids.

+ Calculate the specific gravity from API gravity

+ Calculate the Barrels of crude oil per metric ton from API Gravity or select a fluid from the preloaded fluids database to perform the calculation

+ Find the classification of oil according to API gravity (Light oil, Medium oil, Heavy oil or Exra heavy oil)

The database has the available liquids below:

Propane

Butane

Gasoline

Kerosene

No. 1 Fuel oil

No. 2 Fuel oil

Jet fuel JP-4

Jet fuel JP-5

Benzene

Gas oils

Jet fuel

Peanut oil

Petroleum oil

Olive oil

Octane
