About Converting Pounds per Teaspoon to Stones per Gallon
Pound per Teaspoon and Stone per 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
stones per gallon = pounds per teaspoon × 54.8571428571
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per teaspoon equals 92026.6961794 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct pound per teaspoon-to-stone per gallon factor of 54.8571428571.
Simple example
1 lb/tsp × 54.85714286 = 54.85714286 st/gal
