Unit definitions
What is a fluid ounce (fl oz)?
The fluid ounce – not to be confused with its weight-measuring cousin – is the chameleon of volume measurements. Used primarily in liquid ingredients, it’s your go-to for anything pourable.
- Symbol: fl oz
- Common uses: Liquid medications, beverage servings, liquid baking ingredients
- Definition: 1/16 of a US liquid pint or 1/128 of a US gallon
What is a tablespoon (tbsp)?
That unassuming spoon in your cutlery drawer? Its standardized version is a kitchen workhorse.
- Symbol: tbsp
- Common uses: Measuring spices, oils, vanilla extract – basically any ingredient where precision matters
- Definition: Exactly 3 teaspoons or ½ fluid ounce
Conversion formula
The beauty here lies in simplicity:
Tablespoons = Fluid ounces × 2
No complex fractions or decimal points. If your recipe calls for 3 fl oz of lemon juice? That’s 6 level tablespoons. Need to reverse it? Divide tablespoons by 2 to get fluid ounces.
Example calculations
- Converting 4 fl oz to tbsp
4 fl oz × 2 = 8 tbsp
Perfect for doubling that pancake recipe - Converting 10 tbsp to fl oz
10 tbsp ÷ 2 = 5 fl oz
Useful when scaling down soup stocks

Historical background
The tablespoon’s origin story begins with actual spoons – imagine medieval cooks using their personal eating utensils to measure ingredients. Standardization didn’t happen until the 19th century when Fannie Farmer’s Boston Cooking-School Cookbook popularized level measurements.
Fluid ounces trace back to the English wine gallon of 1707. American colonists brought the concept with them, eventually creating the US customary system. Fun fact: UK fluid ounces are about 4% larger than their US counterparts, which matters for cocktail enthusiasts but less so for your casual cooks.
