About Converting Grams per Cup to Grams per Imperial gallon
Gram per Cup and Gram 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
grams per imperial gallon = grams per cup × 19.2151988081
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cup equals 4.22675283773 base units, and 1 gram per imperial gallon equals 0.219969248299 base units, so dividing one by the other gives the direct gram per cup-to-gram per imperial gallon factor of 19.2151988081.
Simple example
1 g/cup × 19.21519881 = 19.21519881 g/imp gal
1 gram per cup = 19.21519881 grams per imperial gallon.
Real-world example
1,000 g/cup × 19.21519881 = 19,215.19881 g/imp gal
1,000 grams per cup = 19,215.19881 grams per imperial gallon.

What is a gram per cup?
Gram per Cup (g/cup) is a unit of density.
What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
Is the gram per cup to gram per imperial gallon conversion exact?
Yes. Both gram per cup and gram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 19.21519881 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.
