About Converting Milligrams per Gallon to Ounces per Cup
Milligram per Gallon and Ounce 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
ounces per cup = milligrams per gallon × 0.00000220462262185
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per gallon equals 0.000264172052358 base units, and 1 ounce per cup equals 119.826427317 base units, so dividing one by the other gives the direct milligram per gallon-to-ounce per cup factor of 0.00000220462262185.
Simple example
1 mg/gal × 0.000002204622622 = 0.0000022046 oz/cup
1 milligram per gallon = 0.0000022046 ounces per cup.
Real-world example
1,000 mg/gal × 0.000002204622622 = 0.0022046226 oz/cup
1,000 milligrams per gallon = 0.0022046226 ounces per cup.

What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
Is the milligram per gallon to ounce per cup conversion exact?
Yes. Both milligram per gallon and ounce per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.000002204622622 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.
