About Converting Troy ounces per Quart to Drams per Quart
Troy ounce per Quart 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 quart × 17.5542857143
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per quart equals 32.8666772069 base units, and 1 dram per quart equals 1.87228792683 base units, so dividing one by the other gives the direct troy ounce per quart-to-dram per quart factor of 17.5542857143.
Simple example
1 oz t/qt × 17.55428571 = 17.55428571 dr/qt
