About Converting Drams per Cup to Troy ounces per Fluid ounce
Dram per Cup and Troy ounce 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
troy ounces per fluid ounce = drams per cup × 0.00712076822917
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 troy ounce per fluid ounce equals 1051.73367062 base units, so dividing one by the other gives the direct dram per cup-to-troy ounce per fluid ounce factor of 0.00712076822917.
