About Converting Stones per Oil barrel to Milligrams per Cup
Stone 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 = stones per oil barrel × 9449.84104167
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per oil barrel equals 39.942142439 base units, and 1 milligram per cup equals 0.00422675283773 base units, so dividing one by the other gives the direct stone per oil barrel-to-milligram per cup factor of 9449.84104167.
Simple example
1 st/bbl × 9449.841042 = 9,449.841042 mg/cup
1 stone per oil barrel = 9,449.841042 milligrams per cup.
Real-world example
1,000 st/bbl × 9449.841042 = 9,449,841.042 mg/cup
1,000 stones per oil barrel = 9,449,841.042 milligrams per cup.

What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
What is a milligram per cup?
Milligram per Cup (mg/cup) is a unit of density.
Is the stone per oil barrel to milligram per cup conversion exact?
Yes. Both stone per oil barrel and milligram per cup are defined by fixed standards rather than physical artifacts, so the factor of 9449.841042 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.
