How Many Tablespoons in 1/8 Cup?
1/8 cup is 2 tablespoons. That's also 6 teaspoons, 1 US fluid ounce or 29.6 mL. By weight it depends on the ingredient: 1/8 cup of all-purpose flour is about 15.6 g, granulated sugar 25 g and butter 28.4 g (USDA FoodData Central).

How to use
- Pick the ingredient.
- Choose USDA, or King Arthur if your recipe comes from their kitchen.
- Read the grams in 1/8 cup, or just use 2 level tablespoons.
The formula and two worked examples
1/8 cup = 16 ÷ 8 = 2 tablespoons and grams in 1/8 cup = grams per cup ÷ 8
Granulated sugar. 200 g per cup ÷ 8 = 25 g. So 2 level tablespoons of sugar weigh about 25 g.
Honey. 339 g per cup ÷ 8 = 42.4 g. Honey weighs nearly three times as much as the same spoonful of flour, which is why sticky ingredients are worth weighing.
How to measure 1/8 cup without a 1/8 cup measure
Most US measuring cup sets stop at 1/4 cup, so use spoons instead:
- 2 level tablespoons, the most accurate option.
- 6 level teaspoons, if your tablespoon is missing.
- Half of a 1/4 cup. Fill the 1/4 cup and pour off half by eye. Fine for liquids, less exact for flour.
- The 1 fl oz line on a liquid measuring cup or a shot glass marked in ounces, for liquids only.
- A coffee scoop, if yours is marked 2 tablespoons. Many are, but sizes vary, so check before you rely on it.
What this tool doesn't cover
It covers US measures only. A UK or Australian 1/8 metric cup is 31.25 mL, slightly more than the US 29.6 mL. Weights assume level spoons and typical US products, so brands and packing change them a little.

Tips
- For butter, 1/8 cup is a quarter of a stick: 2 tablespoon marks on the wrapper.
- Spoon flour into the tablespoon and level it with a knife. Scooping packs it and adds up to 20%.
- For oil and other liquids, a 1 fl oz shot glass with a line is quicker than two spoons.
