About Converting Drams per Teaspoon to Pounds per Teaspoon
Dram per Teaspoon and Pound 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
pounds per teaspoon = drams per teaspoon × 0.00390625
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per teaspoon equals 359.479281951 base units, and 1 pound per teaspoon equals 92026.6961794 base units, so dividing one by the other gives the direct dram per teaspoon-to-pound per teaspoon factor of 0.00390625.
Simple example
1 dr/tsp × 0.00390625 = 0.00390625 lb/tsp
1 dram per teaspoon = 0.00390625 pounds per teaspoon.
Real-world example
1,000 dr/tsp × 0.00390625 = 3.90625 lb/tsp
1,000 drams per teaspoon = 3.90625 pounds per teaspoon.

Use the reverse factor: 1 pound per teaspoon equals 256 drams per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
What is a pound per teaspoon?
Pound per Teaspoon (lb/tsp) is a unit of density.
Is the dram per teaspoon to pound per teaspoon conversion exact?
Yes. Both dram per teaspoon and pound per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.00390625 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.
