About Converting Drams per Gallon to Long tons per Fluid ounce
Dram per Gallon and Long ton per Fluid ounce 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 fluid ounce = drams per gallon × 1.362392e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 long ton per fluid ounce equals 34356633.2403 base units, so dividing one by the other gives the direct dram per gallon-to-long ton per fluid ounce factor of 1.362392e-8.
Simple example
1 dr/gal × 1.362392e-8 = 1.362392e-8 long ton/fl oz
1 dram per gallon = 1.362392e-8 long tons per fluid ounce.
