About Converting Pounds per Imperial gallon to Megagrams per Teaspoon
Pound per Imperial gallon and Megagram per Teaspoon 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
megagrams per teaspoon = pounds per imperial gallon × 4.917899e-7
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 megagram per teaspoon equals 202884136.211 base units, so dividing one by the other gives the direct pound per imperial gallon-to-megagram per teaspoon factor of 4.917899e-7.
Simple example
1 lb/imp gal × 4.917899e-7 = 4.917899e-7 Mg/tsp
1 pound per imperial gallon = 4.917899e-7 megagrams per teaspoon.
Real-world example
1,000 lb/imp gal × 4.917899e-7 = 0.0004917899 Mg/tsp
1,000 pounds per imperial gallon = 0.0004917899 megagrams per teaspoon.
