The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.

API gravity express the gravity or density of crude oil and liquid petroleum products. API is devised jointly by the American Petroleum Institute and the NIST - National Institute of Standards and Technology . The measuring scale is calibrated in terms of degrees API. °API = (141.5 / SG) - …

The measuring scale is calibrated in terms of degrees API; it is calculated as follows: The higher the API gravity, the lighter the compound. Light crudes generally exceed 38 degrees API and …

API gravity is short for American Petroleum Institute gravity, an inverse measure that is used to determine the weight of petroleum liquids in comparison to water. If a liquid has API gravity of more than 10 it is considered a light oil that floats on water.

The widely used American Petroleum Institute (API) gravity scale is based on pure water, with an arbitrarily assigned API gravity of 10°. (API gravities are unitless and are often referred to in degrees; they are calculated by multiplying the inverse of the specific gravity of a liquid at…

Aug 1, 2022 · With the API gravity calculator, you can determine the API gravity of any liquid petroleum product by simply indicating its density. You can also use this tool to convert specific gravity to API gravity and vice versa.

In the early years of the petroleum industry, the American Petroleum Institute (API) adopted the API gravity (°API) as a measure of the crude oil density. The API gravity is calculated from the following equation: °API = 141.5 SG15.6°C/15.6°C − 131.5.

Dec 12, 2024 · API gravity, short for American Petroleum Institute gravity, is a scale used to measure the density of crude oil and other liquids. It is a widely recognized and industry-standard method for measuring the gravity or density of petroleum products.

The API gravity is an arbitrary scale developed by the American Petroleum Institute (API) as a measure of the density of petroleum liquids at 60 °F (15.56 °C) relative to the density of water at 60 °F. The values of API gravity are expressed as degrees API and denoted as °API.

Aug 4, 2015 · The specific gravity table published by the American Petroleum Institute (API) is a tool for determining the relative density of various types of oil. While it has no units of measurement, an oil’s rating is expressed as API degrees.
