pound-force per cubic foot
Unit weightexact by definition
The pound-force per cubic foot is the customary unit of specific weight, equal to 157.087... N/m³. The definition is exact because the pound-force and the foot are exactly defined, though the decimal does not terminate. Water is 62.4 lbf/ft³ and normal-weight concrete about 150 lbf/ft³.
Watch out: The abbreviation pcf is used loosely for both pound per cubic foot (a density) and pound-force per cubic foot (a specific weight). They are numerically equal on Earth and dimensionally different, so the ambiguity is usually harmless in customary calculations and becomes a real problem the moment the value is converted to SI. Decide which quantity you have before converting.
