About Converting Pounds per Cubic Centimeter to Grains per Imperial gallon
Pound per Cubic Centimeter and Grain 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
grains per imperial gallon = pounds per cubic centimeter × 31822630
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 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-grain per imperial gallon factor of 31822630.
Simple example
1 lb/cm3 × 31822630 = 31,822,630 gr/imp gal
1 pound per cubic centimeter = 31,822,630 grains per imperial gallon.
Real-world example
1,000 lb/cm3 × 31822630 = 31,822,630,000 gr/imp gal
1,000 pounds per cubic centimeter = 31,822,630,000 grains per imperial gallon.

Frequently asked questions
How many grains per imperial gallon are in 1 pound per cubic centimeter?
1 pound per cubic centimeter equals 31,822,630 grains per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic centimeter to grain per imperial gallon?
Multiply the pound per cubic centimeter value by 31822630. The converter above does this instantly to whatever precision you set.
How do I convert grain per imperial gallon back to pound per cubic centimeter?
Use the reverse factor: 1 grain per imperial gallon equals 3.142418e-8 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 grain per imperial gallon?
Grain per Imperial gallon (gr/imp gal) is a unit of density.
Is the pound per cubic centimeter to grain per imperial gallon conversion exact?
Yes. Both pound per cubic centimeter and grain per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 31822630 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.
