About Converting Carats per Teaspoon to Drams per Teaspoon
Carat per Teaspoon 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 = carats per teaspoon × 0.112876678239
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 teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct carat per teaspoon-to-dram per teaspoon factor of 0.112876678239.
Simple example
1 ct/tsp × 0.1128766782 = 0.1128766782 dr/tsp
1 carat per teaspoon = 0.1128766782 drams per teaspoon.
Real-world example
1,000 ct/tsp × 0.1128766782 = 112.8766782 dr/tsp
1,000 carats per teaspoon = 112.8766782 drams per teaspoon.
