About Converting Ounces per Gallon to Megagrams per Fluid ounce
Ounce per Gallon and Megagram per Fluid ounce 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 fluid ounce = ounces per gallon × 2.214806e-7
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 fluid ounce equals 33814022.7018 base units, so dividing one by the other gives the direct ounce per gallon-to-megagram per fluid ounce factor of 2.214806e-7.
Simple example
1 oz/gal × 2.214806e-7 = 2.214806e-7 Mg/fl oz
1 ounce per gallon = 2.214806e-7 megagrams per fluid ounce.
Real-world example
1,000 oz/gal × 2.214806e-7 = 0.0002214806 Mg/fl oz
1,000 ounces per gallon = 0.0002214806 megagrams per fluid ounce.

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.
