About Converting Stones per Oil barrel to Megagrams per Cup
Stone per Oil barrel and Megagram 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
megagrams per cup = stones per oil barrel × 0.00000944984104167
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 megagram per cup equals 4226752.83773 base units, so dividing one by the other gives the direct stone per oil barrel-to-megagram per cup factor of 0.00000944984104167.
Simple example
1 st/bbl × 0.000009449841042 = 0.0000094498 Mg/cup
1 stone per oil barrel = 0.0000094498 megagrams per cup.
Real-world example
1,000 st/bbl × 0.000009449841042 = 0.009449841 Mg/cup
1,000 stones per oil barrel = 0.009449841 megagrams per cup.

What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
What is a megagram per cup?
Megagram per Cup (Mg/cup) is a unit of density.
Is the stone per oil barrel to megagram per cup conversion exact?
Yes. Both stone per oil barrel and megagram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.000009449841042 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.
