About Converting Ounces per Gallon to Megagrams per Cup
Ounce per Gallon and Megagram 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. Ounce per Gallon is most often used for used to express dilution rates on many us pesticide, herbicide, and household cleaning product labels, which commonly specify a number of fluid ounces of concentrate per gallon of water.
Formula
megagrams per cup = ounces per gallon × 0.00000177184519531
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per gallon equals 7.48915170731 base units, and 1 megagram per cup equals 4226752.83773 base units, so dividing one by the other gives the direct ounce per gallon-to-megagram per cup factor of 0.00000177184519531.
Simple example
1 oz/gal × 0.000001771845195 = 0.0000017718 Mg/cup
1 ounce per gallon = 0.0000017718 megagrams per cup.
Real-world example
1,000 oz/gal × 0.000001771845195 = 0.0017718452 Mg/cup
1,000 ounces per gallon = 0.0017718452 megagrams per cup.

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.
