About Converting Stones per Teaspoon to Short tons per Cup
Stone per Teaspoon and Short ton 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
short tons per cup = stones per teaspoon × 0.336
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per teaspoon equals 1288373.74651 base units, and 1 short ton per cup equals 3834445.67414 base units, so dividing one by the other gives the direct stone per teaspoon-to-short ton per cup factor of 0.336.
Simple example
1 st/tsp × 0.336 = 0.336 ton/cup
1 stone per teaspoon = 0.336 short tons per cup.
Real-world example
1,000 st/tsp × 0.336 = 336 ton/cup
1,000 stones per teaspoon = 336 short tons per cup.

Multiply the stone per teaspoon value by 0.336. The converter above does this instantly to whatever precision you set.
How do I convert short ton per cup back to stone per teaspoon?
Use the reverse factor: 1 short ton per cup equals 2.976190476 stones per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per teaspoon?
Stone per Teaspoon (st/tsp) is a unit of density.
What is a short ton per cup?
Short ton per Cup (ton/cup) is a unit of density.
Is the stone per teaspoon to short ton per cup conversion exact?
Yes. Both stone per teaspoon and short ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.336 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.
