About Converting Troy ounces per Quart to Drams per Liter
Troy ounce per Quart and Dram per Liter 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 liter = troy ounces per quart × 18.5494067393
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 liter equals 1.77184519531 base units, so dividing one by the other gives the direct troy ounce per quart-to-dram per liter factor of 18.5494067393.
Simple example
1 oz t/qt × 18.54940674 = 18.54940674 dr/L
1 troy ounce per quart = 18.54940674 drams per liter.
Real-world example
1,000 oz t/qt × 18.54940674 = 18,549.40674 dr/L
