How Many Milliliters in a Teaspoon
Quick Scoop
Ever found yourself mid-recipe, staring at a teaspoon and wondering, “How many milliliters does this tiny thing actually hold?” You’re not alone — it’s one of the most searched kitchen conversions on forums and cooking pages in 2026! Let’s clear it up once and for all with a pinch of context and a dash of precision.
💧 The Simple Answer
Teaspoon (tsp)| Milliliters (mL)
---|---
1 teaspoon (U.S.)| 4.93 mL
1 teaspoon (U.K./Metric)**| 5 mL
Most modern recipes, especially those written outside the U.S., assume 1 teaspoon = 5 mL. That’s the standard used in medicine dosing cups, nutrition labels, and baking guides today.
🧁 Why the Difference Exists
Before measurements were standardized, a “teaspoon” varied by country.
- In the U.S. , it was officially defined as 1/3 tablespoon = 4.92892 mL.
- In most other countries , the metric system rounded this up to 5 mL for simplicity.
Today, kitchen measuring spoons are manufactured to metric standards, so unless your utensils are antique, it’s safe to measure 1 tsp = 5 mL.
