About Converting Milligrams per Imperial gallon to Slugs per Cup
Milligram per Imperial gallon and Slug 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
slugs per cup = milligrams per imperial gallon × 3.566019e-9
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 slug per cup equals 61684.8206534 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-slug per cup factor of 3.566019e-9.
Simple example
1 mg/imp gal × 3.566019e-9 = 3.566019e-9 slug/cup
1 milligram per imperial gallon = 3.566019e-9 slugs per cup.
Real-world example
1,000 mg/imp gal × 3.566019e-9 = 0.000003566 slug/cup
1,000 milligrams per imperial gallon = 0.000003566 slugs per cup.

What is a milligram per imperial gallon?
Milligram per Imperial gallon (mg/imp gal) is a unit of density.
What is a slug per cup?
Slug per Cup (slug/cup) is a unit of density.
Is the milligram per imperial gallon to slug per cup conversion exact?
Yes. Both milligram per imperial gallon and slug per cup are defined by fixed standards rather than physical artifacts, so the factor of 3.566019e-9 used above is exact to as many digits as you choose to display.
