About Converting Milligrams per Fluid ounce to Milligrams per Teaspoon
Milligram per Fluid ounce 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 = milligrams per fluid ounce × 0.166666666667
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 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct milligram per fluid ounce-to-milligram per teaspoon factor of 0.166666666667.
Simple example
1 mg/fl oz × 0.1666666667 = 0.1666666667 mg/tsp
1 milligram per fluid ounce = 0.1666666667 milligrams per teaspoon.
Real-world example
1,000 mg/fl oz × 0.1666666667 = 166.6666667 mg/tsp
1,000 milligrams per fluid ounce = 166.6666667 milligrams per teaspoon.

Frequently asked questions
How many milligrams per teaspoon are in 1 milligram per fluid ounce?
1 milligram per fluid ounce equals 0.1666666667 milligrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per fluid ounce to milligram per teaspoon?
Multiply the milligram per fluid ounce value by 0.1666666667. The converter above does this instantly to whatever precision you set.
How do I convert milligram per teaspoon back to milligram per fluid ounce?
Use the reverse factor: 1 milligram per teaspoon equals 6 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 milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
Is the milligram per fluid ounce to milligram per teaspoon conversion exact?
Yes. Both milligram per fluid ounce and milligram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 0.1666666667 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.
