About Converting Drams per Quart to Carats per Tablespoon
Dram per Quart and Carat 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
carats per tablespoon = drams per quart × 0.138425405884
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per quart equals 1.87228792683 base units, and 1 carat per tablespoon equals 13.5256090807 base units, so dividing one by the other gives the direct dram per quart-to-carat per tablespoon factor of 0.138425405884.
Simple example
1 dr/qt × 0.1384254059 = 0.1384254059 ct/tbsp
1 dram per quart = 0.1384254059 carats per tablespoon.
Real-world example
1,000 dr/qt × 0.1384254059 = 138.4254059 ct/tbsp
1,000 drams per quart = 138.4254059 carats per tablespoon.

What is a dram per quart?
Dram per Quart (dr/qt) is a unit of density.
What is a carat per tablespoon?
Carat per Tablespoon (ct/tbsp) is a unit of density.
Is the dram per quart to carat per tablespoon conversion exact?
Yes. Both dram per quart and carat per tablespoon are defined by fixed standards rather than physical artifacts, so the factor of 0.1384254059 used above is exact to as many digits as you choose to display.
