About Converting Carats per Cup to Drams per Imperial gallon
Carat per Cup and Dram per Imperial 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 imperial gallon = carats per cup × 2.16894781315
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 imperial gallon equals 0.389751455715 base units, so dividing one by the other gives the direct carat per cup-to-dram per imperial gallon factor of 2.16894781315.
Simple example
1 ct/cup × 2.168947813 = 2.168947813 dr/imp gal
1 carat per cup = 2.168947813 drams per imperial gallon.
Real-world example
1,000 ct/cup × 2.168947813 = 2,168.947813 dr/imp gal
