About Converting Carats per Imperial gallon to Pounds per Cubic foot
Carat 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 = carats per imperial gallon × 0.00274644631216
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per imperial gallon equals 0.0439938496598 base units, and 1 pound per cubic foot equals 16.018463374 base units, so dividing one by the other gives the direct carat per imperial gallon-to-pound per cubic foot factor of 0.00274644631216.
Simple example
1 ct/imp gal × 0.002746446312 = 0.0027464463 lb/ft3
1 carat per imperial gallon = 0.0027464463 pounds per cubic foot.
Real-world example
1,000 ct/imp gal × 0.002746446312 = 2.746446312 lb/ft3
1,000 carats per imperial gallon = 2.746446312 pounds per cubic foot.

What is a carat per imperial gallon?
Carat per Imperial gallon (ct/imp gal) is a unit of density.
What is a pound per cubic foot?
Pound per Cubic foot (lb/ft3) measures density. The US customary unit for expressing density, commonly used in construction and engineering material specifications. It is classified as a US customary density unit.
Is the carat per imperial gallon to pound per cubic foot conversion exact?
Yes. Both carat per imperial gallon and pound per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 0.002746446312 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
