About Converting Drams per Oil barrel to Stones per Cubic foot
Dram per Oil barrel and Stone per Cubic foot 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 cubic foot = drams per oil barrel × 0.0000496952027564
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 cubic foot equals 224.258487235 base units, so dividing one by the other gives the direct dram per oil barrel-to-stone per cubic foot factor of 0.0000496952027564.
Simple example
1 dr/bbl × 0.00004969520276 = 0.0000496952 st/ft3
1 dram per oil barrel = 0.0000496952 stones per cubic foot.
Real-world example
1,000 dr/bbl × 0.00004969520276 = 0.0496952028 st/ft3
1,000 drams per oil barrel = 0.0496952028 stones per cubic foot.
