How Many Ounces in a Teaspoon?

Quick Scoop

Ever wondered how many ounces are in a single teaspoon? It’s a simple question — but it trips up plenty of people in the kitchen! Here’s a clear breakdown so you can measure accurately next time you’re baking or stirring up something new.

🧂 Basic Conversion

A teaspoon (tsp) is one of the smallest common units of volume in cooking. In U.S. measurements, it converts to fluid ounces as follows:

Unit Equivalent in Ounces (fl oz) Equivalent in Milliliters (mL)
1 teaspoon 0.1667 fl oz ~4.93 mL
3 teaspoons (1 tablespoon) 0.5 fl oz ~14.79 mL
6 teaspoons (2 tablespoons) 1 fl oz ~29.57 mL
So, if you’re doing a quick estimate: 👉 **1 teaspoon ≈ 1/6 of a fluid ounce.**

🍰 Helpful Cooking Tip

When converting dry ingredients, keep in mind that ounces (oz) can mean weight , not volume. For example:

  • 1 teaspoon of sugar weighs differently than 1 teaspoon of oil or salt.
  • Always check if your recipe means fluid ounces (volume) or ounces (weight).

🧮 Example Conversion

Let’s say your recipe calls for 2 ounces of lemon juice , but you only have a teaspoon handy.
Since 1 fl oz = 6 tsp, that means:
2 fl oz × 6 tsp = 12 tsp total. So, you’d need 12 teaspoons of lemon juice to make 2 fluid ounces.

💡 Trending Kitchen Hack (2026 Edition)

In food forums and cooking TikToks early this year, home chefs are swapping traditional measuring spoons for digital kitchen scales that automatically toggle between mL, tsp, and oz modes. It’s a fast-track way to prevent measurement mix-ups — especially for liquid-heavy recipes or international conversions. TL;DR:
1 teaspoon = 0.1667 fl oz (≈ 4.93 mL)
6 teaspoons = 1 fl oz
