About Converting Stones per Cup to Megagrams per Oil barrel
Stone per Cup 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 = stones per cup × 4.26739701696
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cup equals 26841.119719 base units, and 1 megagram per oil barrel equals 6289.81077043 base units, so dividing one by the other gives the direct stone per cup-to-megagram per oil barrel factor of 4.26739701696.
Simple example
1 st/cup × 4.267397017 = 4.267397017 Mg/bbl
1 stone per cup = 4.267397017 megagrams per oil barrel.
Real-world example
1,000 st/cup × 4.267397017 = 4,267.397017 Mg/bbl
1,000 stones per cup = 4,267.397017 megagrams per oil barrel.

What is a stone per cup?
Stone per Cup (st/cup) 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 stone per cup to megagram per oil barrel conversion exact?
Yes. Both stone per cup and megagram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 4.267397017 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.
