About Converting Pounds per Imperial gallon to Stones per Cubic Centimeter
Pound per Imperial gallon and Stone 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
stones per cubic centimeter = pounds per imperial gallon × 0.0000157120891642
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 stone per cubic centimeter equals 6350293.18 base units, so dividing one by the other gives the direct pound per imperial gallon-to-stone per cubic centimeter factor of 0.0000157120891642.
Simple example
1 lb/imp gal × 0.00001571208916 = 0.0000157121 st/cm3
1 pound per imperial gallon = 0.0000157121 stones per cubic centimeter.
Real-world example
1,000 lb/imp gal × 0.00001571208916 = 0.0157120892 st/cm3
1,000 pounds per imperial gallon = 0.0157120892 stones per cubic centimeter.

What is a pound per imperial gallon?
Pound per Imperial gallon (lb/imp gal) is a unit of density.
What is a stone per cubic centimeter?
Stone per Cubic Centimeter (st/cm3) is a unit of density.
Is the pound per imperial gallon to stone per cubic centimeter conversion exact?
Yes. Both pound per imperial gallon and stone per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.00001571208916 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.
