Tsp To Ml Converter

Teaspoons vs. Milliliters: A Volume Showdown

The teaspoon (tsp) is a customary unit of volume, especially common in recipes in the United States. The milliliter (ml), a core unit of the metric system, is used worldwide for both cooking and scientific measurements. Since both are units of volume, converting between them is a direct mathematical process, essential for anyone needing to switch between measurement systems.

This calculator uses the standard US teaspoon for all conversions. It's good to be aware that other definitions (like the UK metric teaspoon) exist, but the US standard is most common in online recipes.

How to Use the Teaspoon to mL Converter

Our tool is designed for quick and accurate results:

1. Enter Your Value: Type the measurement you have into the appropriate box—either "Teaspoons (tsp)" or "Milliliters (ml)".
2. Get an Instant Result: The calculator automatically provides the converted value in the other box as you type.
3. Swap Units: Use the swap button () to easily switch the input and output fields.

The Conversion Formula

The conversion is based on the standard definition of a US teaspoon:

1 US Teaspoon = 4.92892 Milliliters (ml)

For most everyday cooking, this is often rounded to 5 ml. Our calculator uses the more precise value for accuracy. The formulas are:

• Milliliters = Teaspoons × 4.92892
• Teaspoons = Milliliters / 4.92892

Practical Example

Suppose you are giving a child a dose of medicine that requires 7.5 ml, but the measuring device you have is only marked in teaspoons.

• Input: Enter "7.5" into the "Milliliters (ml)" field.
• Result: The "Teaspoons (tsp)" field will immediately show approximately 1.52 tsp. This tells you that you need just over one and a half teaspoons.

Importance of Accurate Volume Conversion

This conversion is critical in many areas:

• Cooking & Baking: To accurately follow international recipes.
• Medicine: For precise dosing of liquid medications, where accuracy can be critical.
• Science & Chemistry: When working with small volumes in a laboratory setting.
