About Converting Pounds per Imperial gallon to Slugs per Quart
Pound per Imperial gallon and Slug 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
slugs per quart = pounds per imperial gallon × 0.0064700762104
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 slug per quart equals 15421.2051633 base units, so dividing one by the other gives the direct pound per imperial gallon-to-slug per quart factor of 0.0064700762104.
Simple example
1 lb/imp gal × 0.00647007621 = 0.0064700762 slug/qt
1 pound per imperial gallon = 0.0064700762 slugs per quart.
Real-world example
1,000 lb/imp gal × 0.00647007621 = 6.47007621 slug/qt
1,000 pounds per imperial gallon = 6.47007621 slugs per quart.
