About Converting Ounces per Gallon to Milligrams per Quart
Ounce per Gallon and Milligram per Quart 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
milligrams per quart = ounces per gallon × 7087.38078125
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 milligram per quart equals 0.00105668820943 base units, so dividing one by the other gives the direct ounce per gallon-to-milligram per quart factor of 7087.38078125.
Simple example
1 oz/gal × 7087.380781 = 7,087.380781 mg/qt
1 ounce per gallon = 7,087.380781 milligrams per quart.
Real-world example
1,000 oz/gal × 7087.380781 = 7,087,380.781 mg/qt
1,000 ounces per gallon = 7,087,380.781 milligrams per quart.

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.
