About Converting Grains per Pint to Stones per Oil barrel
Grain per Pint 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 = grains per pint × 0.00342857142857
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per pint equals 0.136944488362 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct grain per pint-to-stone per oil barrel factor of 0.00342857142857.
Simple example
1 gr/pt × 0.003428571429 = 0.0034285714 st/bbl
1 grain per pint = 0.0034285714 stones per oil barrel.
Real-world example
1,000 gr/pt × 0.003428571429 = 3.428571429 st/bbl
1,000 grains per pint = 3.428571429 stones per oil barrel.

What is a grain per pint?
Grain per Pint (gr/pt) 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 grain per pint to stone per oil barrel conversion exact?
Yes. Both grain per pint and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.003428571429 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.
