About Converting Grams per Quart to Pounds per Imperial gallon
Gram 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 = grams per quart × 0.0105905654939
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per quart equals 1.05668820943 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct gram per quart-to-pound per imperial gallon factor of 0.0105905654939.
Simple example
1 g/qt × 0.01059056549 = 0.0105905655 lb/imp gal
1 gram per quart = 0.0105905655 pounds per imperial gallon.
Real-world example
1,000 g/qt × 0.01059056549 = 10.59056549 lb/imp gal
1,000 grams per quart = 10.59056549 pounds per imperial gallon.
