About Converting Troy ounces per Cup to Drams per Quart
Troy ounce per Cup 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 cup × 70.2171428571
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per cup equals 131.466708828 base units, and 1 dram per quart equals 1.87228792683 base units, so dividing one by the other gives the direct troy ounce per cup-to-dram per quart factor of 70.2171428571.
Simple example
1 oz t/cup × 70.21714286 = 70.21714286 dr/qt
1 troy ounce per cup = 70.21714286 drams per quart.
Real-world example
1,000 oz t/cup × 70.21714286 = 70,217.14286 dr/qt
