About Converting Long tons per Oil barrel to Stones per Quart
Long ton per Oil barrel and Stone per Quart 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 quart = long tons per oil barrel × 0.952380952381
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 stone per quart equals 6710.27992975 base units, so dividing one by the other gives the direct long ton per oil barrel-to-stone per quart factor of 0.952380952381.
Simple example
1 long ton/bbl × 0.9523809524 = 0.9523809524 st/qt
1 long ton per oil barrel = 0.9523809524 stones per quart.
Real-world example
1,000 long ton/bbl × 0.9523809524 = 952.3809524 st/qt
1,000 long tons per oil barrel = 952.3809524 stones per quart.

How do I convert stone per quart back to long ton per oil barrel?
Use the reverse factor: 1 stone per quart equals 1.05 long tons per oil barrel. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per oil barrel?
Long ton per Oil barrel (long ton/bbl) is a unit of density.
What is a stone per quart?
Stone per Quart (st/qt) is a unit of density.
Is the long ton per oil barrel to stone per quart conversion exact?
Yes. Both long ton per oil barrel and stone per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.9523809524 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.
