About Converting Ounces per Liter to Milligrams per Teaspoon
Ounce per Liter 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 = ounces per liter × 139.732576703
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per liter equals 28.349523125 base units, and 1 milligram per teaspoon equals 0.202884136211 base units, so dividing one by the other gives the direct ounce per liter-to-milligram per teaspoon factor of 139.732576703.
Simple example
1 oz/L × 139.7325767 = 139.7325767 mg/tsp
1 ounce per liter = 139.7325767 milligrams per teaspoon.
Real-world example
1,000 oz/L × 139.7325767 = 139,732.5767 mg/tsp
1,000 ounces per liter = 139,732.5767 milligrams per teaspoon.

Frequently asked questions
How many milligrams per teaspoon are in 1 ounce per liter?
1 ounce per liter equals 139.7325767 milligrams per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per liter to milligram per teaspoon?
Multiply the ounce per liter value by 139.7325767. The converter above does this instantly to whatever precision you set.
How do I convert milligram per teaspoon back to ounce per liter?
Use the reverse factor: 1 milligram per teaspoon equals 0.0071565273 ounces per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per liter?
Ounce per Liter (oz/L) is a unit of density.
What is a milligram per teaspoon?
Milligram per Teaspoon (mg/tsp) is a unit of density.
Is the ounce per liter to milligram per teaspoon conversion exact?
Yes. Both ounce per liter and milligram per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 139.7325767 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.
