About Converting Ounces per Quart to Troy ounces per Gallon
Ounce per Quart and Troy ounce 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
troy ounces per gallon = ounces per quart × 3.64583333333
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 troy ounce per gallon equals 8.21666930173 base units, so dividing one by the other gives the direct ounce per quart-to-troy ounce per gallon factor of 3.64583333333.
