Df 4 Instrument of Asphalt Degree Measurement

API gravity - Wikipedia

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 that of water (also known as specific gravity).
