When to use this converter
Best for spices, extracts, and leaveners where a few mL make a difference.
Common mistakes to avoid
- A teaspoon is 5 mL; coffee/tea spoons from flatware sets often differ—use a measuring spoon.
- For strong flavors (vanilla, chili), measure level, not heaping.
Quick example 1¾ tsp vanilla extract ≈ 8.75 mL. Round to 9 mL if your spoon isn’t lab-precise.
