Converting teaspoon/tablespoon measurements to mL?
It's actually understandable why this would be confusing to non-Americans, because the terms "teaspoon" and "tablespoon" actually have two meanings - one in cooking and one in dining.

Historically, teaspoons and tablespoons were simply two types of silverware.  Teaspoons were literally for stirring tea or other liquids.  Tablespoons were used for serving.  So yes, the terms actually do refer to the purpose of the spoon.

They are also now used as cooking measurements across most of North America and possibly other regions:


A standard teaspoon (1 tsp) is approximately 5 mL (4.9 mL)
A standard tablespoon (1 tbsp) is 3 tsp or approximately 15 mL (14.7 mL)


For future reference, I use Google as my go-to resource for unit conversions whenever I don't know or can't remember the exact ratios.  For example, you can type the phrase 2 tbsp in mL directly into the search box and it will give you the answer (29.57 mL).
