About Converting Drams per Quart to Troy ounces per Fluid ounce
Dram per Quart 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 quart × 0.00178019205729
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per quart equals 1.87228792683 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 quart-to-troy ounce per fluid ounce factor of 0.00178019205729.
Simple example
1 dr/qt × 0.001780192057 = 0.0017801921 oz t/fl oz
1 dram per quart = 0.0017801921 troy ounces per fluid ounce.
Real-world example
1,000 dr/qt × 0.001780192057 = 1.780192057 oz t/fl oz
1,000 drams per quart = 1.780192057 troy ounces per fluid ounce.
