For spices and leavening, teaspoons are usually more accurate than cup fractions.
How Many mL Are in a Teaspoon?
Quick explanation
Use teaspoons to mL when recipe steps are in spoons but you want metric values for measuring jugs, prep tools, or nutrition tracking. This conversion is common for spices, syrups, and small liquid additions where consistency matters. The converter gives exact output with practical guidance for everyday cooking, especially when metric labels need to match a spoon-based recipe step for liquids or extracts in small amounts during prep. It is helpful when you want one clear metric target. For reverse conversion, open mL to teaspoons.

About these units
Teaspoon (tsp)
Teaspoons are widely used in recipe instructions for small ingredient amounts.
- 1 tsp = 5 mL (project standard).
- Teaspoons are useful for precise additions of strong ingredients.
Millilitre (mL)
mL output is useful when your measuring tools and product labels are metric.
- 1000 mL = 1 L.
- Metric values are convenient for repeatable prep and scaling.
Tips
If a conversion looks “off,” check whether you mixed weight (oz) and volume (fl oz).
Dry measuring cups and liquid measuring cups can read differently; both can be correct.
