About Converting Pounds per Cubic Centimeter to Pounds per Imperial gallon
Pound per Cubic Centimeter and Pound per Imperial gallon 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 imperial gallon = pounds per cubic centimeter × 4546.09
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic centimeter equals 453592.37 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-pound per imperial gallon factor of 4546.09.
Simple example
1 lb/cm3 × 4546.09 = 4,546.09 lb/imp gal
1 pound per cubic centimeter = 4,546.09 pounds per imperial gallon.
Real-world example
1,000 lb/cm3 × 4546.09 = 4,546,090 lb/imp gal
1,000 pounds per cubic centimeter = 4,546,090 pounds per imperial gallon.

Frequently asked questions
How many pounds per imperial gallon are in 1 pound per cubic centimeter?
1 pound per cubic centimeter equals 4,546.09 pounds per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic centimeter to pound per imperial gallon?
Multiply the pound per cubic centimeter value by 4546.09. The converter above does this instantly to whatever precision you set.
How do I convert pound per imperial gallon back to pound per cubic centimeter?
Use the reverse factor: 1 pound per imperial gallon equals 0.0002199692 pounds per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
Is the pound per cubic centimeter to pound per imperial gallon conversion exact?
Yes. Both pound per cubic centimeter and pound per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 4546.09 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.
