About Converting Ounces per Teaspoon to Decagrams per Cup
Ounce 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 = ounces per teaspoon × 136.077711
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per teaspoon equals 5751.66851121 base units, and 1 decagram per cup equals 42.2675283773 base units, so dividing one by the other gives the direct ounce per teaspoon-to-decagram per cup factor of 136.077711.
Simple example
1 oz/tsp × 136.077711 = 136.077711 dag/cup
1 ounce per teaspoon = 136.077711 decagrams per cup.
Real-world example
1,000 oz/tsp × 136.077711 = 136,077.711 dag/cup
1,000 ounces per teaspoon = 136,077.711 decagrams per cup.

Multiply the ounce per teaspoon value by 136.077711. The converter above does this instantly to whatever precision you set.
How do I convert decagram per cup back to ounce per teaspoon?
Use the reverse factor: 1 decagram per cup equals 0.0073487421 ounces per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per teaspoon?
Ounce per Teaspoon (oz/tsp) is a unit of density.
What is a decagram per cup?
Decagram per Cup (dag/cup) is a unit of density.
Is the ounce per teaspoon to decagram per cup conversion exact?
Yes. Both ounce per teaspoon and decagram per cup are defined by fixed standards rather than physical artifacts, so the factor of 136.077711 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.
