What Is A Tablespoon?

The tablespoon is a common measurement of ingredients used in cooking and baking.

Tablespoon is equivalent to 0.5 fluid ounce or 15 mL. A tablespoon is commonly abbreviated in recipes as  “tbsp” or “tbs”.  Similar to the teaspoon, a tablespoon is used to measure dry ingredients like dried herbs and spices, baking powder, baking soda and cream of tartar. It can also be used to measure liquids like pure vanilla extract, honey, maple syrup, mustard and mayonnaise.

What Is An Ounce?

Ounce is used in the U.S. and Britain to measure the “weight” of something (like flour and sugar). The word “ounce” comes from the Latin word “unica” meaning “one-twelfth” and it was abbreviated as “oz” back in the 1500s. The abbreviation “oz” comes from the Italian word “onza”, which also means “ounce”. 

What is a Fluid Ounce?

“Fluid ounce” (fl oz or fl. oz.) is from the Imperial and U.S. Customary System measurements system that is used in the measurement of the volume of liquid ingredients (like milk, water or juice). The term fluid ounce is often abbreviated as fl. oz or fl oz, which means either a single fluid ounce or fluid ounces (both “ounce” and “ounces” can be abbreviated as “oz”).

Fluid ounces are still used in the United States Customary System of measurements, while the United Kingdom stopped using this legal unit of measure and started using the Metric System in 2000.

Imperial (US) System vs Metric System

Different countries use different volume and weight measurements. Some countries use the Imperial System while some use the Metric System.

The United States still uses the Imperial System for measurements (which was developed and used in the United Kingdom around 1826), where most countries like the United Kingdom, Australia, Canada have since adopted the metric system using measurements like grams, meters, liters, kilograms and kilometers. There aren’t significant differences in volume between the Imperial (US) and Metric measuring systems. 

For the most part, the Metric System has replaced the imperial system in countries who once used it. The United States is one of the few countries in the world who has yet to switch to the Metric System of measurements. But if you’re in a pinch, if a recipe is written using the Metric system, you can easily use US teaspoons and tablespoons to convert to metric measurements. 

Converting US Standard to Metric System [Approximate Measurements]

  • 2 tablespoons = 1/8 cup = 1 fluid ounce = 29 mL
  • 4 tablespoons = 1/4 cup = 2 fluid ounces = 59 mL
  • 8 tablespoons = 1/2 cup = 4 fluid ounces = 118 mL
  • 12 tablespoons = 3/4 cup = 6 fluid ounces = 177 mL
  • 16 tablespoons = 1 cup = 8 fluid ounces = 237 mL

The US Customary System

The United States Customary System (U.S. Customary System) is a system of weights and measures used in the United States and some other countries. This system includes units for measuring length (inches, feet, yards and miles), weight (ounce, pound, ton), and capacity (teaspoons, tablespoon, cups, pints, quarts, gallons).
