About Converting Grains per Quart to Grains per Oil barrel
Grain 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 = grains per quart × 168
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per quart equals 0.0684722441811 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct grain per quart-to-grain per oil barrel factor of 168.
Simple example
1 gr/qt × 168 = 168 gr/bbl
1 grain per quart = 168 grains per oil barrel.
Real-world example
1,000 gr/qt × 168 = 168,000 gr/bbl
1,000 grains per quart = 168,000 grains per oil barrel.

Frequently asked questions
How many grains per oil barrel are in 1 grain per quart?
1 grain per quart equals 168 grains per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert grain per quart to grain per oil barrel?
Multiply the grain per quart value by 168. The converter above does this instantly to whatever precision you set.
How do I convert grain per oil barrel back to grain per quart?
Use the reverse factor: 1 grain per oil barrel equals 0.005952381 grains per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per quart?
Grain per Quart (gr/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 grain per quart to grain per oil barrel conversion exact?
Yes. Both grain per quart and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 168 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.
