About Converting Ounces per Cubic foot to Drams per Gallon
Ounce per Cubic foot and Dram per Gallon 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 gallon = ounces per cubic foot × 2.13888888889
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic foot equals 1.00115396087 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct ounce per cubic foot-to-dram per gallon factor of 2.13888888889.
Simple example
1 oz/ft3 × 2.138888889 = 2.138888889 dr/gal
1 ounce per cubic foot = 2.138888889 drams per gallon.
Real-world example
1,000 oz/ft3 × 2.138888889 = 2,138.888889 dr/gal
1,000 ounces per cubic foot = 2,138.888889 drams per gallon.
