About Converting Carats per Teaspoon to Drams per Gallon
Carat per Teaspoon and Dram per Gallon 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 gallon = carats per teaspoon × 86.6892888873
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per teaspoon equals 40.5768272422 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct carat per teaspoon-to-dram per gallon factor of 86.6892888873.
Simple example
1 ct/tsp × 86.68928889 = 86.68928889 dr/gal
1 carat per teaspoon = 86.68928889 drams per gallon.
Real-world example
1,000 ct/tsp × 86.68928889 = 86,689.28889 dr/gal
1,000 carats per teaspoon = 86,689.28889 drams per gallon.
