About Converting Milligrams per Gallon to Ounces per Quart
Milligram per Gallon and Ounce 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. Both are mass per volume density units.
Formula
ounces per quart = milligrams per gallon × 0.0000088184904874
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 quart equals 29.9566068292 base units, so dividing one by the other gives the direct milligram per gallon-to-ounce per quart factor of 0.0000088184904874.
Simple example
1 mg/gal × 0.000008818490487 = 0.0000088185 oz/qt
1 milligram per gallon = 0.0000088185 ounces per quart.
Real-world example
1,000 mg/gal × 0.000008818490487 = 0.0088184905 oz/qt
1,000 milligrams per gallon = 0.0088184905 ounces per quart.

Multiply the milligram per gallon value by 0.000008818490487. The converter above does this instantly to whatever precision you set.
How do I convert ounce per quart back to milligram per gallon?
Use the reverse factor: 1 ounce per quart equals 113,398.0925 milligrams per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
What is a ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
Is the milligram per gallon to ounce per quart conversion exact?
Yes. Both milligram per gallon and ounce per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.000008818490487 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.
