About Converting Imperial hundredweights per Imperial gallon to Pounds per Cubic foot

Imperial hundredweight per Imperial gallon and Pound per Cubic foot both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.

Formula

pounds per cubic foot = imperial hundredweights per imperial gallon × 697.629571413

This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per imperial gallon equals 11174.9537383 base units, and 1 pound per cubic foot equals 16.018463374 base units, so dividing one by the other gives the direct imperial hundredweight per imperial gallon-to-pound per cubic foot factor of 697.629571413.

Simple example

1 long cwt/imp gal × 697.6295714 = 697.6295714 lb/ft3

1 imperial hundredweight per imperial gallon = 697.6295714 pounds per cubic foot.

Real-world example

1,000 long cwt/imp gal × 697.6295714 = 697,629.5714 lb/ft3

1,000 imperial hundredweights per imperial gallon = 697,629.5714 pounds per cubic foot.
