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
