About Converting Micrograms per Teaspoon to Drams per Teaspoon
Microgram per Teaspoon and Dram 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
drams per teaspoon = micrograms per teaspoon × 5.643834e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 microgram per teaspoon equals 0.000202884136211 base units, and 1 dram per teaspoon equals 359.479281951 base units, so dividing one by the other gives the direct microgram per teaspoon-to-dram per teaspoon factor of 5.643834e-7.
Simple example
1 ug/tsp × 5.643834e-7 = 5.643834e-7 dr/tsp
1 microgram per teaspoon = 5.643834e-7 drams per teaspoon.
Real-world example
1,000 ug/tsp × 5.643834e-7 = 0.0005643834 dr/tsp
1,000 micrograms per teaspoon = 0.0005643834 drams per teaspoon.

Frequently asked questions
How many drams per teaspoon are in 1 microgram per teaspoon?
1 microgram per teaspoon equals 5.643834e-7 drams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert microgram per teaspoon to dram per teaspoon?
Multiply the microgram per teaspoon value by 5.643834e-7. The converter above does this instantly to whatever precision you set.
How do I convert dram per teaspoon back to microgram per teaspoon?
Use the reverse factor: 1 dram per teaspoon equals 1,771,845.195 micrograms per teaspoon. You can also use the swap control in the converter above to flip the direction instantly.
What is a microgram per teaspoon?
Microgram per Teaspoon (ug/tsp) is a unit of density.
What is a dram per teaspoon?
Dram per Teaspoon (dr/tsp) is a unit of density.
Is the microgram per teaspoon to dram per teaspoon conversion exact?
Yes. Both microgram per teaspoon and dram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 5.643834e-7 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.
