About Converting Carats per Quart to Grains per Oil barrel
Carat per Quart and Grain 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
grains per oil barrel = carats per quart × 518.527240659
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct carat per quart-to-grain per oil barrel factor of 518.527240659.
Simple example
1 ct/qt × 518.5272407 = 518.5272407 gr/bbl
1 carat per quart = 518.5272407 grains per oil barrel.
Real-world example
1,000 ct/qt × 518.5272407 = 518,527.2407 gr/bbl
1,000 carats per quart = 518,527.2407 grains per oil barrel.

What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
Is the carat per quart to grain per oil barrel conversion exact?
Yes. Both carat per quart and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 518.5272407 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.
