About Converting Carats per Oil barrel to Long tons per Cubic foot
Carat per Oil barrel and Long ton per Cubic foot 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 cubic foot = carats per oil barrel × 3.505893e-8
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 long ton per cubic foot equals 35881.3579577 base units, so dividing one by the other gives the direct carat per oil barrel-to-long ton per cubic foot factor of 3.505893e-8.
Simple example
1 ct/bbl × 3.505893e-8 = 3.505893e-8 long ton/ft3
1 carat per oil barrel = 3.505893e-8 long tons per cubic foot.
Real-world example
1,000 ct/bbl × 3.505893e-8 = 0.0000350589 long ton/ft3
1,000 carats per oil barrel = 0.0000350589 long tons per cubic foot.
