About Converting Troy ounces per Teaspoon to Grains per Cup
Troy ounce per Teaspoon and Grain per Cup 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 cup = troy ounces per teaspoon × 23040
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 cup equals 0.273888976724 base units, so dividing one by the other gives the direct troy ounce per teaspoon-to-grain per cup factor of 23040.
Simple example
1 oz t/tsp × 23040 = 23,040 gr/cup
1 troy ounce per teaspoon = 23,040 grains per cup.
Real-world example
1,000 oz t/tsp × 23040 = 23,040,000 gr/cup
1,000 troy ounces per teaspoon = 23,040,000 grains per cup.

What is a troy ounce per teaspoon?
Troy ounce per Teaspoon (oz t/tsp) is a unit of density.
What is a grain per cup?
Grain per Cup (gr/cup) is a unit of density.
Is the troy ounce per teaspoon to grain per cup conversion exact?
Yes. Both troy ounce per teaspoon and grain per cup are defined by fixed standards rather than physical artifacts, so the factor of 23040 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.
