About Converting Troy ounces per Cup to Drams per Fluid ounce
Troy ounce per Cup and Dram per Fluid ounce 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 fluid ounce = troy ounces per cup × 2.19428571429
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 fluid ounce equals 59.9132136584 base units, so dividing one by the other gives the direct troy ounce per cup-to-dram per fluid ounce factor of 2.19428571429.
