About Converting Kilograms per Teaspoon to Drams per Cup
Kilogram per Teaspoon and Dram 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
drams per cup = kilograms per teaspoon × 27090.4027773
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per teaspoon equals 202884.136211 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct kilogram per teaspoon-to-dram per cup factor of 27090.4027773.
Simple example
1 kg/tsp × 27090.40278 = 27,090.40278 dr/cup
1 kilogram per teaspoon = 27,090.40278 drams per cup.
Real-world example
1,000 kg/tsp × 27090.40278 = 27,090,402.78 dr/cup
1,000 kilograms per teaspoon = 27,090,402.78 drams per cup.

How do I convert dram per cup back to kilogram per teaspoon?
Use the reverse factor: 1 dram per cup equals 0.0000369134 kilograms per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilogram per teaspoon?
Kilogram per Teaspoon (kg/tsp) is a unit of density.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the kilogram per teaspoon to dram per cup conversion exact?
Yes. Both kilogram per teaspoon and dram per cup are defined by fixed standards rather than physical artifacts, so the factor of 27090.40278 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.
