About Converting Carats per Oil barrel to Long tons per Gallon
Carat per Oil barrel and Long ton per 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
long tons per gallon = carats per oil barrel × 4.686698e-9
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 gallon equals 268411.19719 base units, so dividing one by the other gives the direct carat per oil barrel-to-long ton per gallon factor of 4.686698e-9.
Simple example
1 ct/bbl × 4.686698e-9 = 4.686698e-9 long ton/gal
1 carat per oil barrel = 4.686698e-9 long tons per gallon.
Real-world example
1,000 ct/bbl × 4.686698e-9 = 0.0000046867 long ton/gal
1,000 carats per oil barrel = 0.0000046867 long tons per gallon.
