API gravity — 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… … Wikipedia
API gravity — An arbitrary scale expressing the gravity, or density, of liquid petroleum products in terms of API degrees. Relationship of the API scale to specific gravity is expressed by the equation ºAPI = (441.5/sp gr 60/60F) 131.5. ASTM D 287 is the… … Petroleum refining glossary
API Gravity — Universally accepted scale, adopted by the API, to express the specific gravity of oils. It serves as a rough measure of quality. The higher the API gravity number, the richer the yield in premium refined products. ► See also API … Financial and business terms
API gravity — American Petroleum Institute measure of specific gravity of crude oil or condensate in degrees. An arbitrary scale expressing the gravity or density of liquid petroleum products. The measuring scale is calibrated in terms of degrees API; it is… … Energy terms
