Milliliters to teaspoons in everyday kitchen language
A milliliter is precise, but it can feel abstract when you are cooking. A teaspoon is easier to picture because it matches the measuring spoon you actually pick up at the counter. Converting mL to tsp turns a small metric amount into something you can measure without pausing the recipe.
This page uses the metric kitchen teaspoon: 5 mL per teaspoon. That makes the conversion simple. Divide milliliters by 5. So 5 mL is 1 teaspoon, 10 mL is 2 teaspoons, and 30 mL is 6 teaspoons.
Quick mL to tsp answers
| Milliliters | Teaspoons | Practical read |
|---|---|---|
| 1 mL | 0.2 tsp | Too small for most spoon sets |
| 2.5 mL | 0.5 tsp | Half teaspoon |
| 5 mL | 1 tsp | One teaspoon |
| 10 mL | 2 tsp | Two teaspoons |
| 15 mL | 3 tsp | One tablespoon in many metric kitchens |
| 30 mL | 6 tsp | Two tablespoons |
Teaspoon, tablespoon, and mL without the confusion
Teaspoons and tablespoons sit next to each other in most kitchen measuring sets, so it helps to understand both at once. With metric spoon measures, 1 tablespoon is 15 mL, which is the same as 3 teaspoons.
| Kitchen measure | Milliliters | Teaspoons |
|---|---|---|
| 1/4 tsp | 1.25 mL | 0.25 tsp |
| 1/2 tsp | 2.5 mL | 0.5 tsp |
| 1 tsp | 5 mL | 1 tsp |
| 1 tbsp | 15 mL | 3 tsp |
| 2 tbsp | 30 mL | 6 tsp |
Medicine caution
A kitchen teaspoon is helpful for understanding volume, but medicine should be measured with the marked dosing tool supplied with the product. Follow the label if it gives mL directly.
When to keep mL instead of teaspoons
Keep milliliters when the amount is very small, when precision matters, or when the label already gives a clear mL amount. Convert to teaspoons when the goal is everyday cooking instruction. For example, 12 mL is 2.4 tsp, but a recipe might say "about 2 1/2 tsp" because that is easier to measure with common spoons.

Frequently asked questions about milliliters to teaspoons conversion
Is one teaspoon 5 mL?
For this kitchen converter, yes: one teaspoon is treated as 5 mL. That is the common metric spoon standard. Some US customary references use about 4.93 mL, so check the source if a recipe is very strict.
Can I use this mL to tsp conversion for medicine?
Use the medicine label and the dosing syringe or cup that came with the product. The 5 mL teaspoon rule is useful for understanding the amount, but household spoons are not reliable dosing tools.
How should I write 1 mL in teaspoons in a recipe?
1 mL is 0.2 tsp. In a recipe, it is often clearer to keep very small amounts in milliliters unless the amount lines up with a practical spoon fraction like 1/4 tsp or 1/2 tsp.
Should I round 7.5 mL to 1.5 tsp?
Yes, if you use the 5 mL teaspoon standard. 7.5 mL is exactly 1.5 teaspoons, which is easy to measure with a 1 tsp plus 1/2 tsp spoon.
Why do recipes sometimes prefer teaspoons over milliliters?
Teaspoons are easier to picture for small kitchen additions such as vanilla, lemon juice, spices, oils, and syrups. Milliliters are better for precise recording, scaling, and packaging.
Which shortcut helps you remember mL to tsp?
Remember 5 mL equals 1 teaspoon. From there, 10 mL is 2 teaspoons, 15 mL is 3 teaspoons, and 30 mL is 6 teaspoons or 2 tablespoons.
