About Converting Milligrams per Imperial gallon to Grams per Cup
Milligram 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 = milligrams per imperial gallon × 0.0000520421365393
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-gram per cup factor of 0.0000520421365393.
Simple example
1 mg/imp gal × 0.00005204213654 = 0.0000520421 g/cup
1 milligram per imperial gallon = 0.0000520421 grams per cup.
Real-world example
1,000 mg/imp gal × 0.00005204213654 = 0.0520421365 g/cup
1,000 milligrams per imperial gallon = 0.0520421365 grams per cup.

What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
What is a gram per cup?
Gram per Cup (g/cup) is a unit of density.
Is the milligram per imperial gallon to gram per cup conversion exact?
Yes. Both milligram per imperial gallon and gram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.00005204213654 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.
