About Converting Grams per Gallon to Pounds per Imperial gallon
Gram per Gallon 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 gallon × 0.00264764137348
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per gallon equals 0.264172052358 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct gram per gallon-to-pound per imperial gallon factor of 0.00264764137348.
Simple example
1 g/gal × 0.002647641373 = 0.0026476414 lb/imp gal
1 gram per gallon = 0.0026476414 pounds per imperial gallon.
Real-world example
1,000 g/gal × 0.002647641373 = 2.647641373 lb/imp gal
1,000 grams per gallon = 2.647641373 pounds per imperial gallon.
