About Converting Drams per Milliliter to Stones per Teaspoon
Dram per Milliliter and Stone per Teaspoon 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
stones per teaspoon = drams per milliliter × 0.00137525714111
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per milliliter equals 1771.84519531 base units, and 1 stone per teaspoon equals 1288373.74651 base units, so dividing one by the other gives the direct dram per milliliter-to-stone per teaspoon factor of 0.00137525714111.
Simple example
1 dr/mL × 0.001375257141 = 0.0013752571 st/tsp
1 dram per milliliter = 0.0013752571 stones per teaspoon.
Real-world example
1,000 dr/mL × 0.001375257141 = 1.375257141 st/tsp
1,000 drams per milliliter = 1.375257141 stones per teaspoon.

Frequently asked questions
How many stones per teaspoon are in 1 dram per milliliter?
1 dram per milliliter equals 0.0013752571 stones per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per milliliter to stone per teaspoon?
Multiply the dram per milliliter value by 0.001375257141. The converter above does this instantly to whatever precision you set.
How do I convert stone per teaspoon back to dram per milliliter?
Use the reverse factor: 1 stone per teaspoon equals 727.1367442 drams per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per milliliter?
Dram per Milliliter (dr/mL) is a unit of density.
What is a stone per teaspoon?
Stone per Teaspoon (st/tsp) is a unit of density.
Is the dram per milliliter to stone per teaspoon conversion exact?
Yes. Both dram per milliliter and stone per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.001375257141 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.
