API gravity meaning in Business Dictionary

American petroleum Institute's inverted scale for denoting the 'lightness' or 'heaviness' of crude essential oils alongside liquid hydrocarbons. Calibrated in API levels (or degrees API), it really is used universally to expresses a crude's relative thickness in an inverse measure less heavy the crude, higher the API gravity, and vice versa because lighter the crude higher its marketplace price. Oil with API more than 30º is termed light; between 22º and 30º, medium; below 22º, heavy; and below 10º, additional heavy. Asphalt normally has actually an API gravity of 8°, Brent Crude of 35.5°, and gas of 50°. Formula: {(141.5 ÷ relative density of the crude (at 15.5°C or 60°F)} - 131.5.
