About Converting Troy ounces per Teaspoon to Grains per Gallon
Troy ounce per Teaspoon and Grain 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
grains per gallon = troy ounces per teaspoon × 368640
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per teaspoon equals 6310.40202373 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct troy ounce per teaspoon-to-grain per gallon factor of 368640.
Simple example
1 oz t/tsp × 368640 = 368,640 gr/gal
1 troy ounce per teaspoon = 368,640 grains per gallon.
Real-world example
1,000 oz t/tsp × 368640 = 368,640,000 gr/gal
1,000 troy ounces per teaspoon = 368,640,000 grains per gallon.

What is a troy ounce per teaspoon?
Troy ounce per Teaspoon (oz t/tsp) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the troy ounce per teaspoon to grain per gallon conversion exact?
Yes. Both troy ounce per teaspoon and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 368640 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
