Teaspoon definition

A teaspoon (abbreviated as "tsp") is a US volume unit equal to ⅓ of a US tablespoon.

1 US teaspoon = 0.17 US fl oz, 0.18 imp fl oz, or 5 milliliters.

1 Australian teaspoon (tsp AU) = 5 milliliters.

Fluid ounce definition

A US fluid ounce (abbreviated as "fl oz," "fl.oz.," or "oz.fl.") is a US customary unit of volume that is equal to ⅛ of a cup.

1 US fluid ounce = 1/128 gallon, 1/16 pint, ⅛ cup, 2 tablespoons, 30 milliliters.

Please, don't confuse a fluid ounce with a dry ounce (oz) which is a unit of weight.

How many ounces in one teaspoon

Let's have a look at how many oz make a tablespoon.

1 teaspoon to fl oz (1 teaspoon to fl oz)

1 teaspoon = 0.17 fluid ounces (US customary system), or

1 teaspoon = 0.17 fl oz

1 imperial teaspoon = 0.625 imperial ounces (Imperial system), or

1 imp teaspoon = 0.21 imp fl oz

How many teaspoons in an oz

1 fl oz to a teaspoon (1 fl oz to tsp)

How many teaspoons in 1 ounce?

1 fl oz = 6 tsp

How to convert teaspoons to ounces

Since one fluid ounce equals 6 teaspoons, to convert US teaspoons to fluid ounces, divide the number of teaspoons by 6, where 6 is a conversion factor:

the teaspoon ÷ 6.

Let's have a look at an example. All the calculations below use the US measurement system.

How many ounces in 3 teaspoons

3 teaspoon ÷ 6 = 0.5 fl oz, so

there is 0.5 fluid ounces in 3 teaspoons.

How many ounces in 6 teaspoons?

There is 1 ounce in 6 teaspoons.

How many ounces in 9 tablespoons?

There are 1.5 ounces in 9 teaspoons.

How many ounces in 12 tablespoons?

There are 2 ounces in 12 teaspoons.

How to convert ounces to teaspoons

To convert ounces to teaspoons, multiply the number of fluid ounces by 6, where 6 is a conversion factor:

the fl oz x 6.

Let's have a look at an example.

How many teaspoons in 1 ounce

1 fl oz x 6 = 6 tbsp, so

there is 6 teaspoon in 1 fluid ounce.

How many dry ounces in a teaspoon

That means that a teaspoon value varies depending on the kind and size of powder or granule.

This conversion is more complicated than converting between volume measurements, so here is a table that will help.

Ingredient	All-purpose flour	Granulated sugar	Table salt	Butter
½ tsp	0.05 oz	0.07 oz	0.1 oz	0.08 oz
1 tsp	0.09 oz	0.15 oz	0.2 oz	0.17 oz
2 tsp	0.18 oz	0.29 oz	0.4 oz	0.33 oz
3 tsp	0.28 oz	0.44 oz	0.6 oz	0.5 oz
4 tsp	0.37 oz	0.59 oz	0.8 oz	0.67 oz
5 tsp	0.46 oz	0.73 oz	1 oz	0.83 oz

Wet ingredients vs. dry ingredients

The measurements for liquid substances should be made with wet measuring cups, but the smaller quantities can also come in graduated measuring spoons.

These ingredients are listed in volume units in recipes: fluid ounces or milliliters (metric system).

But there is a lot of confusion about ingredient measurements in recipes, especially with liquids.

Some ingredients, such as water, milk, oil, cream, etc., can be listed in ounces.

The rule of thumb is that if a wet ingredient is listed in oz., it is a fluid ounce that should be measured in a wet measuring cup.

Dry ingredients listed in cups should be measured with dry measuring cups.

If a recipe calls for flour, sugar, chocolate chips, etc., in ounce measurement, you should use a kitchen scale.

For a quick reminder, measuring cups, teaspoons, and tablespoons are all units of measurement.

That means you cannot use your favorite coffee mug, a teacup, or an ordinary dinner spoon to measure ingredients.
