Milliliters to Teaspoons Converter
Convert milliliters to teaspoons and vice versa with our free volume converter. Perfect for cooking, baking, medicine dosage, and kitchen measurements. Supports US, Metric, and Imperial teaspoon definitions.
What Is a Milliliter?
A milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter. It is commonly used in cooking, baking, medicine, and science to measure small quantities of liquid. One milliliter is also equal to one cubic centimeter (cc).
A teaspoon (tsp) is a common unit of volume used in cooking and baking. There are three different definitions:
- US Teaspoon: 1 tsp = 4.92892 mL — the most common in US recipes.
- Metric Teaspoon: 1 tsp = 5 mL — used in metric countries.
- Imperial Teaspoon: 1 tsp = 5.91939 mL — used in the UK and Commonwealth countries.
1 tablespoon (tbsp) = 3 teaspoons in all systems.
How Does the mL to Teaspoons Converter Work?
The converter uses these formulas:
mL to teaspoons: tsp = mL ÷ tsp_per_mL
teaspoons to mL: mL = tsp × tsp_per_mL
Where tsp_per_mL depends on the teaspoon type:
US: 4.92892 mL, Metric: 5 mL, Imperial: 5.91939 mL
