About Converting Long tons per Oil barrel to Milligrams per Cup
Long ton per Oil barrel and Milligram per Cup 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
milligrams per cup = long tons per oil barrel × 1511974.56667
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per oil barrel equals 6390.74279023 base units, and 1 milligram per cup equals 0.00422675283773 base units, so dividing one by the other gives the direct long ton per oil barrel-to-milligram per cup factor of 1511974.56667.
Simple example
1 long ton/bbl × 1511974.567 = 1,511,974.567 mg/cup
1 long ton per oil barrel = 1,511,974.567 milligrams per cup.
Real-world example
1,000 long ton/bbl × 1511974.567 = 1,511,974,567 mg/cup
1,000 long tons per oil barrel = 1,511,974,567 milligrams per cup.

What is a long ton per oil barrel?
Long ton per Oil barrel (long ton/bbl) is a unit of density.
What is a milligram per cup?
Milligram per Cup (mg/cup) is a unit of density.
Is the long ton per oil barrel to milligram per cup conversion exact?
Yes. Both long ton per oil barrel and milligram per cup are defined by fixed standards rather than physical artifacts, so the factor of 1511974.567 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.
