About Converting Pounds per Teaspoon to Grams per Gallon
Pound per Teaspoon and Gram 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
grams per gallon = pounds per teaspoon × 348358.94016
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 gram per gallon equals 0.264172052358 base units, so dividing one by the other gives the direct pound per teaspoon-to-gram per gallon factor of 348358.94016.
Simple example
1 lb/tsp × 348358.9402 = 348,358.9402 g/gal
1 pound per teaspoon = 348,358.9402 grams per gallon.
Real-world example
1,000 lb/tsp × 348358.9402 = 348,358,940.2 g/gal
1,000 pounds per teaspoon = 348,358,940.2 grams per gallon.

What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
What is a gram per gallon?
Gram per Gallon (g/gal) is a unit of density.
Is the pound per teaspoon to gram per gallon conversion exact?
