Ingredient converter
A cup of flour and a cup of honey do not weigh the same. Pick the ingredient, type an amount in cups, spoons or grams, and see it in grams, ounces, cups, tablespoons and teaspoons.

How to use it
- Type an amount and choose whether it is in cups, tablespoons, teaspoons or grams.
- Pick the ingredient from the list.
- Choose the US cup or the 250 mL metric cup that your recipe uses.
- Read the weight in grams and ounces, and the same amount in every kitchen volume unit.
How it works
Each ingredient has a weight for one US cup. The tool turns your amount into a volume, multiplies it by the ingredient’s density (the cup weight divided by 236.5882365 mL) and prints the weight. Going from grams to cups divides by that density. One US cup is 16 tablespoons or 48 teaspoons; a metric cup uses 15 mL tablespoons and 5 mL teaspoons.
Source of the weights: King Arthur Baking, Ingredient Weight Chart (kingarthurbaking.com/learn/ingredient-weight-chart). Values are for one US cup, for example:
| Ingredient |
Grams per US cup |
| All-purpose flour |
120 |
| Granulated sugar |
198 |
| Brown sugar, packed |
213 |
| Powdered sugar |
113 |
| Butter |
226 |
| Honey |
336 |
| Water or milk |
227 |
Worked example
A US recipe asks for 2¼ cups of all-purpose flour and you want grams. 2.25 × 120 g = 270 g. For 100 g of granulated sugar going back to cups: 100 ÷ 198 = 0.505 cup, a little over ½ cup (8 tablespoons).
Tips
- Weigh when you can. Scale readings are more repeatable than cups, which is why this tool exists for the times you cannot.
- Packed brown sugar and loosely poured powdered sugar are listed as the chart describes them; sift or pack differently and the weight changes.
- Liquids like milk and cream are close to water at 227 g per cup, but honey and syrups are about 1.4 to 1.5 times heavier.
- To scale a whole recipe, use the recipe scaler; for pure volume units see the cooking converter.
Frequently asked questions
Where do the gram weights come from?
All 41 values come from one source, the King Arthur Baking ingredient weight chart. Each is the weight of one US cup. Where the chart lists another portion, such as 8 tablespoons of butter or 1 tablespoon of honey, the tool scales that portion to a cup. Other brands and methods of measuring give slightly different numbers.
How much does a cup of all-purpose flour weigh?
The chart gives 120 g (4¼ oz) per US cup. How hard flour is packed into a cup changes its weight, which is why bakers prefer to weigh it.
What is the difference between the US cup and the metric cup?
A US cup is 236.59 mL and a metric cup is 250 mL, about 6% more. For the metric cup this tool keeps the same density and scales it to 250 mL, and it counts a tablespoon as 15 mL and a teaspoon as 5 mL. In US mode the spoons are 1/16 and 1/48 of a US cup.
Why is a cup of butter 226 g and not 227 g?
The chart lists 8 tablespoons (half a cup) of butter as 113 g, so a full cup is 226 g. Many packs show 227 g for two sticks because each stick is rounded up from 113.4 g. The difference is under half a percent.
Can I trust the result for very small amounts?
The arithmetic is exact, but a household teaspoon of salt or flour varies by several percent from how it is packed and leveled. For quantities under a tablespoon, use the result as a guide, and weigh anything that matters, such as yeast or salt in bread.
