About Converting Stones per Cup to Troy ounces per Gallon
Stone per Cup 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 = stones per cup × 3266.66666667
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cup equals 26841.119719 base units, and 1 troy ounce per gallon equals 8.21666930173 base units, so dividing one by the other gives the direct stone per cup-to-troy ounce per gallon factor of 3266.66666667.
Simple example
1 st/cup × 3266.666667 = 3,266.666667 oz t/gal
1 stone per cup = 3,266.666667 troy ounces per gallon.
Real-world example
1,000 st/cup × 3266.666667 = 3,266,666.667 oz t/gal
1,000 stones per cup = 3,266,666.667 troy ounces per gallon.
