About Converting Grams per Imperial gallon to Grains per Cubic Centimeter
Gram per Imperial gallon and Grain 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
grains per cubic centimeter = grams per imperial gallon × 0.00339464426638
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 grain per cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct gram per imperial gallon-to-grain per cubic centimeter factor of 0.00339464426638.
Simple example
1 g/imp gal × 0.003394644266 = 0.0033946443 gr/cm3
1 gram per imperial gallon = 0.0033946443 grains per cubic centimeter.
Real-world example
1,000 g/imp gal × 0.003394644266 = 3.394644266 gr/cm3
1,000 grams per imperial gallon = 3.394644266 grains per cubic centimeter.

Frequently asked questions
How many grains per cubic centimeter are in 1 gram per imperial gallon?
1 gram per imperial gallon equals 0.0033946443 grains per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert gram per imperial gallon to grain per cubic centimeter?
Multiply the gram per imperial gallon value by 0.003394644266. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to gram per imperial gallon?
Use the reverse factor: 1 grain per cubic centimeter equals 294.5816768 grams per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
Is the gram per imperial gallon to grain per cubic centimeter conversion exact?
Yes. Both gram per imperial gallon and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.003394644266 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.
