About Converting Carats per Cup to Long tons per Oil barrel
Carat per Cup and Long ton per Oil barrel 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
long tons per oil barrel = carats per cup × 0.000132277357311
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 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct carat per cup-to-long ton per oil barrel factor of 0.000132277357311.
Simple example
1 ct/cup × 0.0001322773573 = 0.0001322774 long ton/bbl
1 carat per cup = 0.0001322774 long tons per oil barrel.
Real-world example
1,000 ct/cup × 0.0001322773573 = 0.1322773573 long ton/bbl
1,000 carats per cup = 0.1322773573 long tons per oil barrel.
