About Converting Carats per Cup to Drams per Tablespoon
Carat per Cup 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 cup × 0.00705479238992
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cup equals 0.845350567546 base units, and 1 dram per tablespoon equals 119.826427317 base units, so dividing one by the other gives the direct carat per cup-to-dram per tablespoon factor of 0.00705479238992.
Simple example
1 ct/cup × 0.00705479239 = 0.0070547924 dr/tbsp
1 carat per cup = 0.0070547924 drams per tablespoon.
Real-world example
1,000 ct/cup × 0.00705479239 = 7.05479239 dr/tbsp
1,000 carats per cup = 7.05479239 drams per tablespoon.
