About Converting Grams per Tablespoon to Pounds per Imperial gallon
Gram per Tablespoon 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 tablespoon × 0.67779619161
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per tablespoon equals 67.6280454037 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct gram per tablespoon-to-pound per imperial gallon factor of 0.67779619161.
Simple example
1 g/tbsp × 0.6777961916 = 0.6777961916 lb/imp gal
1 gram per tablespoon = 0.6777961916 pounds per imperial gallon.
Real-world example
1,000 g/tbsp × 0.6777961916 = 677.7961916 lb/imp gal
1,000 grams per tablespoon = 677.7961916 pounds per imperial gallon.
