What is a teaspoon?
A teaspoon (abbreviated as "tsp") is a US volume unit equal to â…“ 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.
What is an ounce?
A US fluid ounce (abbreviated as "fl oz," "fl oz.," or "oz.fl.") is a US customary unit of volume that is equal to â…› of a cup.
1 US fluid ounce = 1/128 gallon, 1/16 pint, â…› cup, 2 tablespoons, 30 milliliters.
Please don't confuse a fluid ounce (fl oz) with a dry ounce (oz), which is a unit of weight.
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 teaspoons?
There are 1.5 ounces in 9 teaspoons.
How many ounces in 12 teaspoons?
There are 2 ounces in 12 teaspoons.
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 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 are 6 teaspoon in 1 fluid ounce.

| 8 fl oz | 48 tsp |
| 9 fl oz | 54 tsp |
| 10 fl oz | 60 tsp |
How many dry ounces in a teaspoon
To convert teaspoons to dry ounces, you need to know the ingredient's density. That means a teaspoon value varies depending on the type and size of the 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 |

How to measure ounces and teaspoons
Getting an accurate measurement comes down to picking the right tool for the ingredient, not just the right unit. Here is how to measure both ounces and teaspoons correctly.
Measuring fluid ounces
For liquids such as water, milk, or oil, use a clear liquid measuring cup marked with fluid ounce lines. Pour the liquid in slowly and check the level at eye level rather than from above, since looking down at an angle can make the amount appear higher or lower than it really is.
Measuring ounces by weight
For dry ingredients like flour, sugar, or chocolate chips, weigh them on a digital kitchen scale instead. Place your bowl or container on the scale, press tare to set it to zero, then add the ingredient until the scale reads the ounce amount your recipe calls for.
Measuring teaspoons
A set of metal or plastic measuring spoons works for both dry and liquid ingredients in teaspoon amounts. Scoop dry ingredients into the spoon and level off the top with the flat edge of a knife for an accurate teaspoon, or fill a liquid right up to the rim without letting it spill over.
Some recipes ask for a "heaping" teaspoon on purpose, which simply means you skip the leveling step and leave the ingredient mounded above the spoon. Unless a recipe says otherwise, though, level measurements are the standard.
