About Converting Carats per Cup to Drams per Gallon
Carat per Cup and Dram per Gallon 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 gallon = carats per cup × 1.80602685182
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 gallon equals 0.468071981707 base units, so dividing one by the other gives the direct carat per cup-to-dram per gallon factor of 1.80602685182.
Simple example
1 ct/cup × 1.806026852 = 1.806026852 dr/gal
1 carat per cup = 1.806026852 drams per gallon.
Real-world example
1,000 ct/cup × 1.806026852 = 1,806.026852 dr/gal
1,000 carats per cup = 1,806.026852 drams per gallon.

What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the carat per cup to dram per gallon conversion exact?
