About Converting Drams per Teaspoon to Troy ounces per Tablespoon
Dram per Teaspoon and Troy ounce per Tablespoon 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 tablespoon = drams per teaspoon × 0.1708984375
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 troy ounce per tablespoon equals 2103.46734124 base units, so dividing one by the other gives the direct dram per teaspoon-to-troy ounce per tablespoon factor of 0.1708984375.
