About Converting Carats per Oil barrel to Drams per Gallon
Carat per Oil barrel and Dram 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
drams per gallon = carats per oil barrel × 0.00268753995806
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 gallon equals 0.468071981707 base units, so dividing one by the other gives the direct carat per oil barrel-to-dram per gallon factor of 0.00268753995806.
Simple example
1 ct/bbl × 0.002687539958 = 0.00268754 dr/gal
1 carat per oil barrel = 0.00268754 drams per gallon.
Real-world example
1,000 ct/bbl × 0.002687539958 = 2.687539958 dr/gal
1,000 carats per oil barrel = 2.687539958 drams per gallon.

What is a carat per oil barrel?
Carat per Oil barrel (ct/bbl) is a unit of density.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the carat per oil barrel to dram per gallon conversion exact?
