Quick Answer: How Many Tablespoons in an Ounce?
In the U.S. measurement system:
- 1 fluid ounce (fl oz) = 2 tablespoons (tbsp)
So if a recipe calls for 2 oz of olive oil, you’ll need 4 tablespoons. Simple!
This conversion applies to liquid ingredients as well as solid ingredients when volume is used (like butter or peanut butter).
Fluid Ounces vs. Dry Ounces
It’s important to know the difference between:
- Fluid ounces (fl oz) – measure volume (used for liquids like milk or oil)
- Ounces (oz) – measure weight (used for dry ingredients like flour or sugar)
When converting fluid ounces to tablespoons, the answer is always:
1 fluid ounce = 2 tablespoons
But if you’re dealing with dry ounces, the conversion will depend on the ingredient’s density.
