About Converting Ounces per Quart to Grams per Gallon
Ounce per Quart and Gram per Gallon 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
grams per gallon = ounces per quart × 113.3980925
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per quart equals 29.9566068292 base units, and 1 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct ounce per quart-to-gram per gallon factor of 113.3980925.
Simple example
1 oz/qt × 113.3980925 = 113.3980925 g/gal
1 ounce per quart = 113.3980925 grams per gallon.
Real-world example
1,000 oz/qt × 113.3980925 = 113,398.0925 g/gal
1,000 ounces per quart = 113,398.0925 grams per gallon.

What is a ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the ounce per quart to gram per gallon conversion exact?
Yes. Both ounce per quart and gram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 113.3980925 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.
