About Converting Pounds per Imperial gallon to Grams per Cubic Millimeter
Pound per Imperial gallon and Gram per Cubic Millimeter 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
grams per cubic millimeter = pounds per imperial gallon × 0.0000997763726631
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 gram per cubic millimeter equals 1000000 base units, so dividing one by the other gives the direct pound per imperial gallon-to-gram per cubic millimeter factor of 0.0000997763726631.
Simple example
1 lb/imp gal × 0.00009977637266 = 0.0000997764 g/mm3
1 pound per imperial gallon = 0.0000997764 grams per cubic millimeter.
Real-world example
1,000 lb/imp gal × 0.00009977637266 = 0.0997763727 g/mm3
1,000 pounds per imperial gallon = 0.0997763727 grams per cubic millimeter.

Multiply the pound per imperial gallon value by 0.00009977637266. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic millimeter back to pound per imperial gallon?
Use the reverse factor: 1 gram per cubic millimeter equals 10,022.41285 pounds per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
What is a gram per cubic millimeter?
Gram per Cubic Millimeter (g/mm3) is a unit of density.
Is the pound per imperial gallon to gram per cubic millimeter conversion exact?
Yes. Both pound per imperial gallon and gram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00009977637266 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.
