About Converting Ounces per Imperial gallon to Grams per Cup
Ounce per Imperial gallon and Gram 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
grams per cup = ounces per imperial gallon × 1.4753697533
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per imperial gallon equals 6.23602329144 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct ounce per imperial gallon-to-gram per cup factor of 1.4753697533.
Simple example
1 oz/imp gal × 1.475369753 = 1.475369753 g/cup
