About Converting Troy ounces per Fluid ounce to Stones per Quart
Troy ounce per Fluid ounce and Stone per Quart 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
stones per quart = troy ounces per fluid ounce × 0.156734693878
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per fluid ounce equals 1051.73367062 base units, and 1 stone per quart equals 6710.27992975 base units, so dividing one by the other gives the direct troy ounce per fluid ounce-to-stone per quart factor of 0.156734693878.
