About Converting Grains per Quart to Megagrams per Oil barrel
Grain per Quart and Megagram 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
megagrams per oil barrel = grains per quart × 0.00001088621688
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 megagram per oil barrel equals 6289.81077043 base units, so dividing one by the other gives the direct grain per quart-to-megagram per oil barrel factor of 0.00001088621688.
Simple example
1 gr/qt × 0.00001088621688 = 0.0000108862 Mg/bbl
1 grain per quart = 0.0000108862 megagrams per oil barrel.
Real-world example
1,000 gr/qt × 0.00001088621688 = 0.0108862169 Mg/bbl
1,000 grains per quart = 0.0108862169 megagrams per oil barrel.

What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
What is a megagram per oil barrel?
Megagram per Oil barrel (Mg/bbl) is a unit of density.
Is the grain per quart to megagram per oil barrel conversion exact?
Yes. Both grain per quart and megagram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.00001088621688 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.
