How much does it weigh?
⅓ cup of all-purpose flour weighs about 42 g (1.5 oz) and has about 152 calories.
Weights use USDA FoodData Central cup measures. How tightly you pack a cup changes the weight, which is why a kitchen scale beats cups for calorie counting.
How many tablespoons are in a cup?
There are 16 tablespoons in a cup, and 3 teaspoons in a tablespoon, so 48 teaspoons in a cup. Everything else follows from those two numbers. Type any amount above, including fractions like 1/3 or 1 1/2, and the converter shows it in every unit.
Cup to tablespoon conversion chart
| Cups | Tablespoons | Teaspoons | Fluid ounces | Millilitres |
|---|---|---|---|---|
| 1 cup | 16 tbsp | 48 tsp | 8 fl oz | 237 ml |
| 3/4 cup | 12 tbsp | 36 tsp | 6 fl oz | 177 ml |
| 2/3 cup | 10 tbsp + 2 tsp | 32 tsp | 5.3 fl oz | 158 ml |
| 1/2 cup | 8 tbsp | 24 tsp | 4 fl oz | 118 ml |
| 1/3 cup | 5 tbsp + 1 tsp | 16 tsp | 2.7 fl oz | 79 ml |
| 1/4 cup | 4 tbsp | 12 tsp | 2 fl oz | 59 ml |
| 1/8 cup | 2 tbsp | 6 tsp | 1 fl oz | 30 ml |
These are US customary measures. A metric cup (used in Australia, Canada and New Zealand) is 250 ml, and a UK tablespoon is the same 15 ml as a metric one.
How many cups are in a litre?
A litre is about 4.2 US cups (1,000 ml ÷ 236.6 ml). Half a litre is just over 2 cups.
Cups to grams: why weight beats volume
A cup measures space, not how much food is in it, so a cup of flour and a cup of sugar weigh very different amounts. The converter's second box shows the weight of a cup (or any amount) of common ingredients using USDA household measures. For example, a cup of all-purpose flour is about 125 g and a cup of granulated sugar is about 200 g.
For calorie counting this matters a lot. How you scoop flour can change a cup's weight by 20% or more, and a "tablespoon" of peanut butter from the jar is often closer to two. If you track what you eat, a cheap kitchen scale is the single best accuracy upgrade. When you can't weigh, Bento Bunny estimates portions from a photo of your plate.
