About Converting Troy ounces per Quart to Drams per Teaspoon
Troy ounce per Quart and Dram per Teaspoon 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 teaspoon = troy ounces per quart × 0.0914285714286
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 teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct troy ounce per quart-to-dram per teaspoon factor of 0.0914285714286.
