About Converting Troy ounces per Fluid ounce to Drams per Quart
Troy ounce per Fluid ounce and Dram 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
drams per quart = troy ounces per fluid ounce × 561.737142857
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 dram per quart equals 1.87228792683 base units, so dividing one by the other gives the direct troy ounce per fluid ounce-to-dram per quart factor of 561.737142857.
