About Converting Grains per Oil barrel to Dram per Cubic inches
Grain per Oil barrel and Dram per Cubic inch 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
dram per cubic inches = grains per oil barrel × 0.00000376947315723
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 dram per cubic inch equals 108.124627774 base units, so dividing one by the other gives the direct grain per oil barrel-to-dram per cubic inch factor of 0.00000376947315723.
Simple example
1 gr/bbl × 0.000003769473157 = 0.0000037695 dr/in3
1 grain per oil barrel = 0.0000037695 dram per cubic inches.
Real-world example
1,000 gr/bbl × 0.000003769473157 = 0.0037694732 dr/in3
1,000 grains per oil barrel = 0.0037694732 dram per cubic inches.
