1/3 Cup is How Many tsp?
How Many Teaspoons in ⅓ Cup?
Alright, so you’re in the kitchen, the recipe calls for ⅓ cup of something—maybe sugar, oil, melted butter—and you’re either:
- Missing your ⅓ cup measuring tool
- Trying to be extra accurate
- Or just plain curious (which we love!)
Whatever the reason, you want to know:
“How many teaspoons are in ⅓ cup?”
Let’s clear it up in a simple, no-stress kind of way.
Quick Answer:
⅓ cup = 16 teaspoons
Yup, exactly 16 teaspoons. That’s your magic number.

The Quick Kitchen Math (Don’t Worry, It’s Easy)
Here’s how we get there:
- 1 cup = 48 teaspoons
- So, if you divide that by 3…
48 ÷ 3 = 16 teaspoons
And just like that:
⅓ cup = 16 tsp
Teaspoon to Cup Conversion Chart
Cups | Teaspoons (tsp) |
---|---|
¼ cup | 12 tsp |
⅓ cup | 16 tsp |
½ cup | 24 tsp |
⅔ cup | 32 tsp |
¾ cup | 36 tsp |
1 cup | 48 tsp |
Pro Tip: 1 tablespoon = 3 teaspoons
So if your recipe talks in tablespoons, you can convert that way too!
Real-Life Example
Let’s say your recipe calls for:
- ⅓ cup of oil, but you’ve only got a teaspoon on hand.
Just scoop out 16 teaspoons, and you’re right on track.
(Yes, it takes a few more scoops, but hey—you get there just the same.)
Does the “⅓ Cup = 16 Teaspoons” Rule Work for Both Wet and Dry Ingredients?
Yes—but with a small asterisk.
Volume stays the same for both wet and dry ingredients
When we say ⅓ cup = 16 teaspoons, we’re talking about volume—not weight. That means this measurement works for both:
- Dry ingredients like sugar, flour, cocoa powder
- Liquid ingredients like oil, milk, or vanilla extract
So if a recipe says ⅓ cup of oil or ⅓ cup of flour, and you’re converting to teaspoons, it’s still 16 teaspoons.
But remember: weight is a different story
Here’s where it can get tricky:
1 teaspoon of flour does not weigh the same as 1 teaspoon of honey or butter. So if you’re working with a recipe that uses grams or ounces (by weight), then teaspoons and cups won’t match unless you know the ingredient’s density.
