About Converting Troy ounces per Gallon to Drams per Oil barrel
Troy ounce per Gallon and Dram 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
drams per oil barrel = troy ounces per gallon × 737.28
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per gallon equals 8.21666930173 base units, and 1 dram per oil barrel equals 0.011144570993 base units, so dividing one by the other gives the direct troy ounce per gallon-to-dram per oil barrel factor of 737.28.
Simple example
1 oz t/gal × 737.28 = 737.28 dr/bbl
1 troy ounce per gallon = 737.28 drams per oil barrel.
Real-world example
1,000 oz t/gal × 737.28 = 737,280 dr/bbl
1,000 troy ounces per gallon = 737,280 drams per oil barrel.
