What is an ml to tsp Converter?

An ml to tsp Converter is a tool used to convert liquid volumes between milliliters (ml) and US teaspoons (tsp). This conversion is frequently needed in cooking, baking, medicine dosage, and other contexts where precise measurements are important. Milliliters are a metric unit of volume, while US teaspoons are a customary unit used primarily in the United States.

ml to tsp Conversion Formulas

The primary conversion factors are:

1 US teaspoon (tsp) = 4.92892 milliliters (ml)
1 milliliter (ml) ≈ 0.202884 US teaspoons (tsp)

Therefore, the formulas for conversion are:

  • Milliliters to US Teaspoons: 
    US Teaspoons = Milliliters × 0.202884
    (or 
    US Teaspoons = Milliliters / 4.92892
    )
  • US Teaspoons to Milliliters: 
    Milliliters = US Teaspoons × 4.92892

Note: These conversions are for US customary teaspoons. Other teaspoon measures (e.g., UK metric teaspoon) can vary.

How to Convert ml to tsp: Example

Example: Convert 15 ml to US teaspoons.

  1. Identify the volume in milliliters: 15 ml
  2. Apply the formula (ml to tsp): US Teaspoons = 15 ml × 0.202884
  3. Calculate: US Teaspoons ≈ 3.04326 tsp

So, 15 milliliters is approximately equal to 3.04 US teaspoons.

Example: Convert 2.5 US teaspoons to ml.

  1. Identify the volume in US teaspoons: 2.5 tsp
  2. Apply the formula (tsp to ml): Milliliters = 2.5 tsp × 4.92892
  3. Calculate: Milliliters ≈ 12.3223 ml

So, 2.5 US teaspoons is approximately equal to 12.32 milliliters.

Common Applications

  • Cooking & Baking: Accurately converting recipe measurements, especially between metric and US customary systems.
  • Medicine: Measuring liquid medication doses, often prescribed in ml but administered with tsp-marked spoons.
  • Chemistry & Science: Laboratory work requiring small volume conversions.
  • Bartending: Mixing drinks where recipes might use either unit.
  • Crafts & DIY: Measuring liquids for various projects like soap making or essential oil blends.
