About Converting Stones per Cup to Troy ounces per Cup
Stone per Cup 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 cup × 204.166666667
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 cup equals 131.466708828 base units, so dividing one by the other gives the direct stone per cup-to-troy ounce per cup factor of 204.166666667.
