About Converting Carats per Oil barrel to Drams per Cup
Carat per Oil barrel and Dram per Cup 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 cup = carats per oil barrel × 0.000167971247379
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per oil barrel equals 0.00125796215409 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct carat per oil barrel-to-dram per cup factor of 0.000167971247379.
Simple example
1 ct/bbl × 0.0001679712474 = 0.0001679712 dr/cup
1 carat per oil barrel = 0.0001679712 drams per cup.
Real-world example
1,000 ct/bbl × 0.0001679712474 = 0.1679712474 dr/cup
1,000 carats per oil barrel = 0.1679712474 drams per cup.
