About Converting Carats per Teaspoon to Drams per Tablespoon
Carat per Teaspoon and Dram 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
drams per tablespoon = carats per teaspoon × 0.338630034716
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 tablespoon equals 119.826427317 base units, so dividing one by the other gives the direct carat per teaspoon-to-dram per tablespoon factor of 0.338630034716.
Simple example
1 ct/tsp × 0.3386300347 = 0.3386300347 dr/tbsp
1 carat per teaspoon = 0.3386300347 drams per tablespoon.
Real-world example
1,000 ct/tsp × 0.3386300347 = 338.6300347 dr/tbsp
1,000 carats per teaspoon = 338.6300347 drams per tablespoon.
