About Converting Ounces per Quart to Pounds per Imperial gallon
Ounce per Quart and Pound per Imperial 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
pounds per imperial gallon = ounces per quart × 0.300237481376
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per quart equals 29.9566068292 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct ounce per quart-to-pound per imperial gallon factor of 0.300237481376.
Simple example
1 oz/qt × 0.3002374814 = 0.3002374814 lb/imp gal
1 ounce per quart = 0.3002374814 pounds per imperial gallon.
Real-world example
1,000 oz/qt × 0.3002374814 = 300.2374814 lb/imp gal
1,000 ounces per quart = 300.2374814 pounds per imperial gallon.
