About Converting Milligrams per Teaspoon to Drams per Cup
Milligram 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 = milligrams per teaspoon × 0.0270904027773
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per teaspoon equals 0.202884136211 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct milligram per teaspoon-to-dram per cup factor of 0.0270904027773.
Simple example
1 mg/tsp × 0.02709040278 = 0.0270904028 dr/cup
1 milligram per teaspoon = 0.0270904028 drams per cup.
Real-world example
1,000 mg/tsp × 0.02709040278 = 27.09040278 dr/cup
1,000 milligrams per teaspoon = 27.09040278 drams per cup.

Frequently asked questions
How many drams per cup are in 1 milligram per teaspoon?
1 milligram per teaspoon equals 0.0270904028 drams per cup, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per teaspoon to dram per cup?
Multiply the milligram per teaspoon value by 0.02709040278. The converter above does this instantly to whatever precision you set.
How do I convert dram per cup back to milligram per teaspoon?
Use the reverse factor: 1 dram per cup equals 36.91344157 milligrams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the milligram per teaspoon to dram per cup conversion exact?
Yes. Both milligram per teaspoon and dram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.02709040278 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.
