About Converting Drams per Fluid ounce to Long tons per Oil barrel
Dram per Fluid ounce and Long ton 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
long tons per oil barrel = drams per fluid ounce × 0.009375
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per fluid ounce equals 59.9132136584 base units, and 1 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct dram per fluid ounce-to-long ton per oil barrel factor of 0.009375.
Simple example
1 dr/fl oz × 0.009375 = 0.009375 long ton/bbl
1 dram per fluid ounce = 0.009375 long tons per oil barrel.
Real-world example
1,000 dr/fl oz × 0.009375 = 9.375 long ton/bbl
1,000 drams per fluid ounce = 9.375 long tons per oil barrel.
