About Converting Stones per Cup to Stones per Oil barrel
Stone per Cup and Stone 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
stones per oil barrel = stones per cup × 672
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 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct stone per cup-to-stone per oil barrel factor of 672.
Simple example
1 st/cup × 672 = 672 st/bbl
1 stone per cup = 672 stones per oil barrel.
Real-world example
1,000 st/cup × 672 = 672,000 st/bbl
1,000 stones per cup = 672,000 stones per oil barrel.

Frequently asked questions
How many stones per oil barrel are in 1 stone per cup?
1 stone per cup equals 672 stones per oil barrel, using the exact defined conversion factor rather than an estimate.
How do I convert stone per cup to stone per oil barrel?
Multiply the stone per cup value by 672. The converter above does this instantly to whatever precision you set.
How do I convert stone per oil barrel back to stone per cup?
Use the reverse factor: 1 stone per oil barrel equals 0.0014880952 stones per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
Is the stone per cup to stone per oil barrel conversion exact?
Yes. Both stone per cup and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 672 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.
