About converting Teaspoons to Milliliters
Teaspoons (tsp) and Milliliters (mL) are both units of volume, so converting between them is a single multiplication: multiply your Teaspoons figure by 4.9289. Ten Teaspoons comes to 49.2892 Milliliters, and a hundred works out at 492.8922 Milliliters.
Rule of thumb: going from Teaspoons to Milliliters multiplies, so the figure always grows — one Teaspoon is already 4.9289 Milliliters. If your answer came out smaller, you have the conversion the wrong way round.
What is a Teaspoon?
The teaspoon is the smallest unit most kitchens ever measure, and it is the base the spoon system is built on — a tablespoon is defined as three of them. It is precise enough for baking powder, salt and vanilla, where the gap between a level spoon and a heaped one decides whether a cake rises. What it should not be used for is medicine: health authorities discourage dosing by teaspoon precisely because the spoons people actually reach for vary widely in size, and recommend a marked oral syringe or dosing cup in milliliters instead.
What is a Milliliter?
A milliliter is one thousandth of a liter, and it is exactly the same size as a cubic centimetre — the "cc" stamped on engines and syringes measures precisely the same thing. That equivalence is quietly useful: a 600 cc motorcycle engine and a 600 mL bottle of water occupy identical volumes, so figures from medicine and mechanics can be compared without any translation at all. The milliliter dominates wherever small quantities must be stated unambiguously: pharmacy, laboratory work, cosmetics and airline carry-on liquid limits are all written in mL rather than in spoons or ounces.
To put both in perspective: a teaspoon is the standard measure for baking powder in a recipe, while a standard wine pour is about 150 milliliters.
