Milliliters to Teaspoons Converter: Convert ml to tsp
Quickly convert milliliters to teaspoons with this handy ml to tsp calculator. Ideal for cooking, baking, and dosage measurements.
Understanding Milliliters to Teaspoons Conversion
Whether you're following a recipe, adjusting a supplement dosage, or working with skincare products, converting milliliters (ml) to teaspoons (tsp) is a common task in both kitchens and laboratories. While milliliters are standardized across the metric system, teaspoons vary by region. That means converting accurately requires more than just basic math—it requires knowing what type of teaspoon is expected in your recipe or measurement system.
Teaspoons are a volume-based unit that originated in the apothecaries’ system but have evolved differently across countries. A US teaspoon is approximately 4.93 milliliters, while a metric or Australian teaspoon is defined as exactly 5 milliliters. Meanwhile, the UK teaspoon is slightly larger, at 5.92 milliliters. These differences matter when converting small but precise volumes, especially in baking or dosing medications where precision can affect outcomes.
Standard Conversion Values
| Region | 1 Teaspoon = ? Milliliters | 1 ml = ? Teaspoons |
|---|---|---|
| US | 4.93 ml | 0.203 tsp |
| UK | 5.92 ml | 0.169 tsp |
| Metric | 5.0 ml | 0.2 tsp |
| Australia | 5.0 ml | 0.2 tsp |
Why Accurate Conversion Matters
Accuracy in small measurements can make a significant difference. For example, using a UK teaspoon instead of a US teaspoon will result in nearly 20% more of an ingredient. This is especially relevant in:
- Baking, where chemical balances are sensitive to volume
- Medication or supplement dosing
- Mixing essential oils or cosmetic ingredients
- Translating international recipes
Conversion Formula
Teaspoons = Milliliters ÷ Conversion Factor
Example: 10 ml ÷ 4.93 = ~2.03 US teaspoons
Common ml to tsp Conversions
- 5 ml = 1 tsp (Metric)
- 10 ml = 2 tsp (US)
- 15 ml = 3 tsp (Australia)
- 20 ml = ~3.38 tsp (UK)
Tips for Converting ml to tsp
- Always verify the region the recipe or label is from
- Use a syringe or graduated measuring tool for milliliters
- Round to the nearest 0.01 tsp for best accuracy
- For dry ingredients, consider using weight instead
