The Essential Conversion: Milliliters to Teaspoons
A guide to accurately converting mL to teaspoons for culinary and medical use.
Understanding the Conversion
The conversion between milliliters (mL) and teaspoons (tsp) is fundamental for anyone who cooks, bakes, or administers liquid medication. The precise value depends on the definition of a teaspoon, which can vary by country.
This calculator uses the United States customary teaspoon, which is defined based on the US fluid ounce and tablespoon.
1 US Teaspoon = 1/3 US Tablespoon ≈ 4.92892 mL
For convenience, especially in cooking and nutrition, this is often rounded to a more memorable number:
1 "Metric" Teaspoon = 5 mL
This 5 mL standard is widely adopted for nutritional labeling and many modern recipes. Our calculator uses the precise 4.92892 value for accuracy, but also notes the 5 mL approximation.
The formulas are:
Teaspoons = Milliliters ÷ 4.92892
Milliliters = Teaspoons × 4.92892
When Precision Matters
While rounding to 5 mL is acceptable for most recipes, it's crucial to be precise in certain situations:
- Medication: Always use a calibrated medical syringe or spoon provided by a pharmacist. A household teaspoon is not an accurate measuring device and can lead to incorrect dosing.
- Scientific Experiments: Laboratory work requires precise measurements. Use graduated cylinders or pipettes instead of culinary teaspoons.
- Baking: For sensitive recipes like bread or pastries, small inaccuracies in leavening agents (like baking soda or yeast) can affect the final result. Using a proper measuring spoon is recommended.
Frequently Asked Questions (FAQ)
- Is a kitchen teaspoon accurate for measuring 5 mL?
- Not necessarily. The size of "teaspoons" in a cutlery set can vary widely. A standardized measuring spoon is designed to hold a more accurate volume and should be used for recipes.
- How many mL in 1/2 teaspoon?
- Using the precise conversion, half a US teaspoon is approximately 2.46 mL. Using the rounded metric standard, it is 2.5 mL.
- How many teaspoons are in a tablespoon?
- In the US system, there are exactly 3 teaspoons in 1 tablespoon.
