About Converting Drams per Pint to Milligrams per Teaspoon
Dram per Pint and Milligram 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
milligrams per teaspoon = drams per pint × 18.4567207845
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per pint equals 3.74457585365 base units, and 1 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct dram per pint-to-milligram per teaspoon factor of 18.4567207845.
Simple example
1 dr/pt × 18.45672078 = 18.45672078 mg/tsp
1 dram per pint = 18.45672078 milligrams per teaspoon.
Real-world example
1,000 dr/pt × 18.45672078 = 18,456.72078 mg/tsp
1,000 drams per pint = 18,456.72078 milligrams per teaspoon.

Frequently asked questions
How many milligrams per teaspoon are in 1 dram per pint?
1 dram per pint equals 18.45672078 milligrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert dram per pint to milligram per teaspoon?
Multiply the dram per pint value by 18.45672078. The converter above does this instantly to whatever precision you set.
How do I convert milligram per teaspoon back to dram per pint?
Use the reverse factor: 1 milligram per teaspoon equals 0.0541808056 drams per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per pint?
Dram per Pint (dr/pt) is a unit of density.
What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
Is the dram per pint to milligram per teaspoon conversion exact?
Yes. Both dram per pint and milligram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 18.45672078 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.
