About Converting Drams per Imperial gallon to Pounds per Quart
Dram per Imperial gallon and Pound per Quart 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
pounds per quart = drams per imperial gallon × 0.000813158383427
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per imperial gallon equals 0.389751455715 base units, and 1 pound per quart equals 479.305709268 base units, so dividing one by the other gives the direct dram per imperial gallon-to-pound per quart factor of 0.000813158383427.
Simple example
1 dr/imp gal × 0.0008131583834 = 0.0008131584 lb/qt
1 dram per imperial gallon = 0.0008131584 pounds per quart.
Real-world example
1,000 dr/imp gal × 0.0008131583834 = 0.8131583834 lb/qt
1,000 drams per imperial gallon = 0.8131583834 pounds per quart.
