About Converting Drams per Oil barrel to Stones per Oil barrel
Dram per Oil barrel 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 = drams per oil barrel × 0.000279017857143
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per oil barrel equals 0.011144570993 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct dram per oil barrel-to-stone per oil barrel factor of 0.000279017857143.
Simple example
1 dr/bbl × 0.0002790178571 = 0.0002790179 st/bbl
1 dram per oil barrel = 0.0002790179 stones per oil barrel.
Real-world example
1,000 dr/bbl × 0.0002790178571 = 0.2790178571 st/bbl
1,000 drams per oil barrel = 0.2790178571 stones per oil barrel.
