About Converting Stones per Gallon to Troy ounces per Cup
Stone per Gallon and Troy ounce per Cup 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 cup = stones per gallon × 12.7604166667
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per gallon equals 1677.56998244 base units, and 1 troy ounce per cup equals 131.466708828 base units, so dividing one by the other gives the direct stone per gallon-to-troy ounce per cup factor of 12.7604166667.
