About Converting Milligrams per Tablespoon to Pounds per Imperial gallon
Milligram 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 = milligrams per tablespoon × 0.00067779619161
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per tablespoon equals 0.0676280454037 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct milligram per tablespoon-to-pound per imperial gallon factor of 0.00067779619161.
Simple example
1 mg/tbsp × 0.0006777961916 = 0.0006777962 lb/imp gal
1 milligram per tablespoon = 0.0006777962 pounds per imperial gallon.
Real-world example
1,000 mg/tbsp × 0.0006777961916 = 0.6777961916 lb/imp gal
1,000 milligrams per tablespoon = 0.6777961916 pounds per imperial gallon.
