About Converting Carats per Teaspoon to Drams per Fluid ounce
Carat per Teaspoon and Dram per Fluid ounce 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 fluid ounce = carats per teaspoon × 0.677260069432
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 fluid ounce equals 59.9132136584 base units, so dividing one by the other gives the direct carat per teaspoon-to-dram per fluid ounce factor of 0.677260069432.
Simple example
1 ct/tsp × 0.6772600694 = 0.6772600694 dr/fl oz
1 carat per teaspoon = 0.6772600694 drams per fluid ounce.
Real-world example
1,000 ct/tsp × 0.6772600694 = 677.2600694 dr/fl oz
1,000 carats per teaspoon = 677.2600694 drams per fluid ounce.
