About Converting Grams per Imperial gallon to Centigrams per Cup
Gram per Imperial gallon and Centigram per Cup 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
centigrams per cup = grams per imperial gallon × 5.20421365393
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 centigram per cup equals 0.0422675283773 base units, so dividing one by the other gives the direct gram per imperial gallon-to-centigram per cup factor of 5.20421365393.
Simple example
1 g/imp gal × 5.204213654 = 5.204213654 cg/cup
1 gram per imperial gallon = 5.204213654 centigrams per cup.
Real-world example
1,000 g/imp gal × 5.204213654 = 5,204.213654 cg/cup
1,000 grams per imperial gallon = 5,204.213654 centigrams per cup.

What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
What is a centigram per cup?
Centigram per Cup (cg/cup) is a unit of density.
Is the gram per imperial gallon to centigram per cup conversion exact?
Yes. Both gram per imperial gallon and centigram per cup are defined by fixed standards rather than physical artifacts, so the factor of 5.204213654 used above is exact to as many digits as you choose to display.
