How To Convert US Ounce (fl oz) to Tablespoon US (tbsp)
Formula: 1 fl oz = 2 tbsp
Example: 7.5 fl oz = 7.5 × 2 = 15 tbsp
To convert by hand, you only need one simple step. Multiply the number of US fluid ounces by 2. This works because a US tablespoon is exactly half of a US fluid ounce. If you ever need to go the other way, you can divide tablespoons by 2.
Quick Answer
1 US fluid ounce (fl oz) = 2 US tablespoons (tbsp)
- 0.5 fl oz = 1 tbsp
- 3 fl oz = 6 tbsp
- 12 fl oz = 24 tbsp
Conversion Formula
US tablespoons (tbsp) = US fluid ounces (fl oz) × 2
US fluid ounces (fl oz) = US tablespoons (tbsp) ÷ 2
Recommended (standard definitions): This 2:1 ratio is exact in US customary measurement because both units are defined from the US gallon. So you do not need rounding for normal cooking and labeling work.
In simple words, every 1 fl oz contains exactly 2 tbsp. So when the ounces go up by 1, the tablespoons go up by 2.
- Write down your value in fl oz.
- Multiply it by 2.
- The result is in tbsp.
