About Converting Stones per Teaspoon to Decagrams per Cup
Stone per Teaspoon and Decagram 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
decagrams per cup = stones per teaspoon × 30481.407264
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 decagram per cup equals 42.2675283773 base units, so dividing one by the other gives the direct stone per teaspoon-to-decagram per cup factor of 30481.407264.
Simple example
1 st/tsp × 30481.40726 = 30,481.40726 dag/cup
1 stone per teaspoon = 30,481.40726 decagrams per cup.
Real-world example
1,000 st/tsp × 30481.40726 = 30,481,407.26 dag/cup
1,000 stones per teaspoon = 30,481,407.26 decagrams per cup.

Frequently asked questions
How many decagrams per cup are in 1 stone per teaspoon?
1 stone per teaspoon equals 30,481.40726 decagrams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert stone per teaspoon to decagram per cup?
Multiply the stone per teaspoon value by 30481.40726. The converter above does this instantly to whatever precision you set.
How do I convert decagram per cup back to stone per teaspoon?
Use the reverse factor: 1 decagram per cup equals 0.0000328069 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 decagram per cup?
Decagram per Cup (dag/cup) is a unit of density.
Is the stone per teaspoon to decagram per cup conversion exact?
Yes. Both stone per teaspoon and decagram per cup are defined by fixed standards rather than physical artifacts, so the factor of 30481.40726 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.
