Heavy Crude Oils: From Geology to Upgrading : an Overview
In 1921, the American Petroleum Institute created the API Gravity Scale, initially
to measure the specific gravity of liquids less dense than water, especially
petroleum. Use of the API Gravity Scale is now extended to the whole range of
specific ...

Composition and Analysis of Heavy Petroleum Fractions
... of petroleum samples are close to those of density and range from about 0.80
for light paraffinic crude oils to about 1.00 for heavy asphaltic ones. To expand
the narrow range in specific gravity values, the API gravity scale was introduced:
...

The A. P. I. gravity scale is an arbitrary one which is related to the specific gravity
of a petroleum oil in accordance with the formula: 141 5 Degrees A- P- L -sp.gr.

The petroleum industry generally uses the American Petroleum Institute (API)
gravity scale to determine the relative density of oil. The scale was devised joindy
by the API and the National Bureau of Standards. The relationship between ...

Bioremediation of Petroleum and Petroleum Products
The API gravity scale (presented as °API) arbitrarily assigns an API gravity of 10°
to pure water. Thus: °API = [141.5/ (specific gravity at 15.6 °C) — 131.5] The scale
is commercially important for ranking petroleum quality: heavy oil typically has ...

Chemistry of Fossil Fuels and Biofuels
The API gravity scale helps emphasize small differences in density between
liquids. For example, two liquids might have specific gravities of 0.84 and 0.88,
which would appear to be a small difference. Yet the API gravities of these liquids
are ...
The oil industry uses the API gravity scale, devised jointly by the American
Petroleum Institute and the National Bureau of Standards. The relationship
between API gravity and specific gravity is an arbitrary one shown by the formula:
Deg.

The oil industry employs the API gravity scale, devised jointly by the American
Petroleum Institute and the National Bureau of Standards. The relationship
between API gravity and the specific gravity is an arbitrary one: l° API gravity
equals l4l.5 ...

On this API gravity scale: ◦API = 141.5 specific gravity (at 60◦F (15.6◦C)) − 131.5 ◦
API gravity ranges over an expanded scale (∼0–60◦), where heavy or dense oils
have low values and less dense oils or condensates have high values.
