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 is thus an inverse measure of a petroleum liquid's density relative to … See more The formula to calculate API gravity from specific gravity (SG) is: $${\displaystyle {\text{API gravity}}={\frac {141.5}{\text{SG}}}-131.5}$$ Conversely, the specific gravity of petroleum liquids … See more In the oil industry, quantities of crude oil are often measured in metric tons. One can calculate the approximate number of barrels per metric ton for a given crude oil based on its API … See more There are advantages to field testing and on-board conversion of measured volumes to volume correction. This method is detailed in ASTM … See more • Comments on API gravity adjustment scale • Instructions for using a glass hydrometer measured in API gravity See more To derive the API gravity, the specific gravity (i.e., density relative to water) is first measured using either the hydrometer, detailed in ASTM D1298 or with the oscillating U-tube method detailed in ASTM D4052. Density … See more Generally speaking, oil with an API gravity between 40 and 45° commands the highest prices. Above 45°, the molecular chains become shorter and less valuable to refineries. Crude oil is classified as light, medium, or heavy according to … See more WebAPI Gravity means the American Petroleum Institute gravity expressed in degrees in relation to liquids, which is a measure of how heavy or light a petroleum liquid is compared to water. If a petroleum liquid's API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier than water and sinks.
