About Converting Milligrams per Quart to Long tons per Oil barrel
Milligram per Quart and Long ton 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
long tons per oil barrel = milligrams per quart × 1.653467e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per quart equals 0.00105668820943 base units, and 1 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct milligram per quart-to-long ton per oil barrel factor of 1.653467e-7.
Simple example
1 mg/qt × 1.653467e-7 = 1.653467e-7 long ton/bbl
1 milligram per quart = 1.653467e-7 long tons per oil barrel.
Real-world example
1,000 mg/qt × 1.653467e-7 = 0.0001653467 long ton/bbl
1,000 milligrams per quart = 0.0001653467 long tons per oil barrel.

What is a milligram per quart?
Milligram per Quart (mg/qt) is a unit of density.
What is a long ton per oil barrel?
Long ton per Oil barrel (long ton/bbl) is a unit of density.
Is the milligram per quart to long ton per oil barrel conversion exact?
Yes. Both milligram per quart and long ton per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 1.653467e-7 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.
