About Converting Troy ounces per Imperial gallon to Milligrams per Cup
Troy ounce per Imperial gallon and Milligram 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
milligrams per cup = troy ounces per imperial gallon × 1618.69138647
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per imperial gallon equals 6.84180841118 base units, and 1 milligram per cup equals 0.00422675283773 base units, so dividing one by the other gives the direct troy ounce per imperial gallon-to-milligram per cup factor of 1618.69138647.
Simple example
1 oz t/imp gal × 1618.691386 = 1,618.691386 mg/cup
1 troy ounce per imperial gallon = 1,618.691386 milligrams per cup.
Real-world example
1,000 oz t/imp gal × 1618.691386 = 1,618,691.386 mg/cup
