About Converting Milligrams per Fluid ounce to Micrograms per Teaspoon
Milligram per Fluid ounce and Microgram 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
micrograms per teaspoon = milligrams per fluid ounce × 166.666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per fluid ounce equals 0.0338140227018 base units, and 1 microgram per teaspoon equals 0.000202884136211 base units, so dividing one by the other gives the direct milligram per fluid ounce-to-microgram per teaspoon factor of 166.666666667.
Simple example
1 mg/fl oz × 166.6666667 = 166.6666667 ug/tsp
1 milligram per fluid ounce = 166.6666667 micrograms per teaspoon.
Real-world example
1,000 mg/fl oz × 166.6666667 = 166,666.6667 ug/tsp
1,000 milligrams per fluid ounce = 166,666.6667 micrograms per teaspoon.

Frequently asked questions
How many micrograms per teaspoon are in 1 milligram per fluid ounce?
1 milligram per fluid ounce equals 166.6666667 micrograms per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per fluid ounce to microgram per teaspoon?
Multiply the milligram per fluid ounce value by 166.6666667. The converter above does this instantly to whatever precision you set.
How do I convert microgram per teaspoon back to milligram per fluid ounce?
Use the reverse factor: 1 microgram per teaspoon equals 0.006 milligrams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per fluid ounce?
Milligram per Fluid ounce (mg/fl oz) is a unit of density.
What is a microgram per teaspoon?
Microgram per Teaspoon (ug/tsp) is a unit of density.
Is the milligram per fluid ounce to microgram per teaspoon conversion exact?
Yes. Both milligram per fluid ounce and microgram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 166.6666667 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.
