Gravity of crude oil or other liquid hydro-carbon, as measured by a system developed by the American Petroleum Institute. API gravity bears an inverse relationship to true specific gravity, but is more familiar than the decimal fractions which result when petroleum is described according to its specific gravity.
A measure of the density of crude oil.... more on: API gravity
An arbitrary scale expressing the gravity or density of liquid petroleum products. The relation between API scale and specific gravity of petroleum oil is expressed by the formula:Degrees API = (141.5 – 131)/Sp.Gr.
Gravity (weight per unit volume) of oils as measured by the API scale. This standard was adopted by the API 5/4/22 as the standard for the American petroleum industries
Gravity (weight per unit volume) of oils as measured by the API scale whereby: API Gravity =141.5 specific gravity at 60o F=- 131.5
The gravity (weight per unit of volume) of crude oil expressed in degrees according to an American Petroleum Institute recommended system. The higher the API gravity, the higher the crude. High-gravity crudes are generally considered more valuable.
the universally accepted scale adopted by the American Petroleum Institute (API) for expressing the density of liquid petroleum products. The higher the API gravity, the lighter the oil.
A system of classifying crude oil based on its specific gravity, whereby the greater the gravity, the lighter the oil. Specifically: 141.5 Degrees API Gravity = ---------------------------- -131.5 Specific Gravity
The standard adopted by API for measuring the density of a liquid, expressed in degrees.
a special gravity scale adopted by the API for expressing density of petroleum products.
The American Petroleum Institute scale used to express the specific gravity of oils.
an American Petroleum Institute scale for crude oil density
A measurement of the gravity (weight per unit volume) of crude oil and other liquid hydrocarbons by a system recommended by the American Petroleum Institute (API). The measuring scale is calibrated in terms of "API degrees." The lower the API gravity, the heavier the oil. The higher the API gravity, the lighter the oil.
Scale, used by the petroleum industry, that is based on reciprocals of specific gravities and, therefore, produces whole numbers having a greater numerical spread. AR Army regulation Army Facilities Component System See AFCS
one of the main quality indicators for pricing crude oil – the higher the API gravity, the lighter the crude. API gravity = 141.5/specific gravity of crude at 60° Fahrenheit – 131.5
The industry standard method of expressing specific gravity of crude oils. Higher API gravities mean lower specific gravity and lighter oils.
An arbitrary scale expressing the gravity or density of liquid petroleum products. The measuring scale is calibrated in terms of degrees API. The higher the API gravity, the lighter the compound. Light crudes generally exceed 38 degrees API and heavy crudes are commonly labeled as all crudes with an API gravity of 22 degrees or below.
A gravity scale established by the American Petroleum Institute and in general use in the petroleum industry, the unit being called "the A.P.I. degree." This unit is defined in terms of specific gravity as follows
a system for measuring density of a liquid to be tested which has been adopted as a standard by API.
A scale expressing the density of petroleum products as established by the American Petroleum Institute.
A scale developed by the American Petroleum Institute for measuring the density or gravity of oil; the higher the number, the lighter the oil.
A measure of the weight of hydrocarbons according to a scale established by the American Petroleum Institute. Crude oils with higher values are lighter and tend to produce larger volumes of high-value lighter products in atmospheric distillation, which makes them relatively more valuable. Crude oil grades that are lower on the API scale tend conversely to be less highly valued because they produce smaller yields of lighter products.
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 a measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids.
