About Converting Grams per Imperial gallon to Pounds per Cubic Centimeter
Gram per Imperial gallon and Pound per Cubic Centimeter 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 centimeter = grams per imperial gallon × 4.849492e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per imperial gallon equals 0.219969248299 base units, and 1 pound per cubic centimeter equals 453592.37 base units, so dividing one by the other gives the direct gram per imperial gallon-to-pound per cubic centimeter factor of 4.849492e-7.
Simple example
1 g/imp gal × 4.849492e-7 = 4.849492e-7 lb/cm3
1 gram per imperial gallon = 4.849492e-7 pounds per cubic centimeter.
Real-world example
1,000 g/imp gal × 4.849492e-7 = 0.0004849492 lb/cm3
1,000 grams per imperial gallon = 0.0004849492 pounds per cubic centimeter.

What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
Is the gram per imperial gallon to pound per cubic centimeter conversion exact?
Yes. Both gram per imperial gallon and pound per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 4.849492e-7 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.
