Units of Measure / How Many Tablespoons in an Ounce

How Many Tablespoons in an Ounce

If you live in a country, where the metric system of units is adopted, you may never need to convert ounces1 to tablespoons2 and vice versa. Most probably, you are used to measure liquids in liters and milliliters. Of course, you can run across teaspoons or tablespoons in some cooking recipes, but you will hardly want to know how much it is in ounces.

But for citizens of the USA and some other countries with the English system, ounces, quarts and gallons are common units of measure, so they should be able to convert tablespoons to them. In fact, you can easily memorize the answer to the question, “How many tablespoons are there in an ounce?”:

If you need to find out how many other units of volume there are in the US tablespoon or the US fluid ounce, the following table below will help you.

One US tablespoon
One US fluid ounce
US Tea-spoons
US Table-spoons
US Fluid Ounces

But if you don’t know what “fluid ounce” means and why we turn particular attentions to US ounces and US tablespoons, go on reading.

Ounces and Tablespoons

First of all, let’s talk about ounces. In this article we discuss units of volume, so we mean the fluid ounce, which is distinct from ounces used for measuring mass. Don’t mix them up.

Then, there are two main definitions of the fluid ounce. They are the imperial fluid ounce (about 28.4 milliliters) and the US customary fluid ounce (about 29.6 milliliters). As it is stated above, converting ounces to tablespoons is important mostly for the USA. That is why we are discussing the US fluid ounce. In fact, imperial ounces are rarely converted to teaspoons or tablespoons.

This table will help you to convert US teaspoons, US tablespoons and US fluid ounces into metric milliliters.

One US teaspoon
About 5 ml
One US tablespoon
About 15 ml
One US fluid ounce
About 30 ml

Remember that in many books the term “ounce” may be used for denoting units of mass and liquid. You just have to take into consideration the context. If it is milk, there is no doubt, they mean the fluid ounce. If it is some dry substance, then it should be the ounce measuring mass.
  1. The ounce (abbr. oz) is a widely-spread non-metric unit of mass or volume (fluid ounce), which is used in various systems and has several definitions. The US fluid ounce equals to about 29.6 milliliters, and the imperial fluid ounce equals to about 28.4 milliliters.
  2. The tablespoon (abbr. Tblspn, Tblsp, Tbsp, Tbs, Tb) – is a common unit of volume measurement used in the USA, Australia and some other countries. The US tablespoon equals to approximately 15 metric milliliters. The Australian variant has about 20 milliliters.
