Formula to Convert mg to tsp

Use this formula for manual conversion:

Teaspoons = (mg) ÷ (density in mg/mL) ÷ 4.93

Where:
- mg = mass in milligrams
- mg/mL = density of the substance
- 4.93 = number of milliliters in 1 teaspoon (approximate)

Example Conversion

Question: How many teaspoons is 300 mg of a liquid with a density of 0.9 mg/mL?

Solution: Apply the formula:

300 ÷ 0.9 ÷ 4.93 ≈ 68.23 tsp

This result shows how important it is to know the density, as the conversion depends on the type of substance.
