About Converting Grains per Gallon to Carats per Oil barrel
Grain per Gallon and Carat 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
carats per oil barrel = grains per gallon × 13.6077711
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 carat per oil barrel equals 0.00125796215409 base units, so dividing one by the other gives the direct grain per gallon-to-carat per oil barrel factor of 13.6077711.
Simple example
1 gr/gal × 13.6077711 = 13.6077711 ct/bbl
1 grain per gallon = 13.6077711 carats per oil barrel.
Real-world example
1,000 gr/gal × 13.6077711 = 13,607.7711 ct/bbl
1,000 grains per gallon = 13,607.7711 carats per oil barrel.

What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a carat per oil barrel?
Carat per Oil barrel (ct/bbl) is a unit of density.
Is the grain per gallon to carat per oil barrel conversion exact?
Yes. Both grain per gallon and carat per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 13.6077711 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
