About Converting Carats per Oil barrel to Pounds per Cup
Carat per Oil barrel and Pound 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
pounds per cup = carats per oil barrel × 6.561377e-7
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 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct carat per oil barrel-to-pound per cup factor of 6.561377e-7.
Simple example
1 ct/bbl × 6.561377e-7 = 6.561377e-7 lb/cup
1 carat per oil barrel = 6.561377e-7 pounds per cup.
Real-world example
1,000 ct/bbl × 6.561377e-7 = 0.0006561377 lb/cup
1,000 carats per oil barrel = 0.0006561377 pounds per cup.
