How the converter reads a recipe
Paste the ingredients, one per line, the way the recipe wrote them. For each line the converter reads the amount, the unit and the ingredient, then rewrites the amount:
Cups of a dry or solid ingredient become grams, using that ingredient’s own weight. A cup of flour is 120 g and a cup of sugar 198 g.
Cups, fluid ounces, pints and quarts of a liquid become milliliters. A cup is written as 240 ml, the rounding metric kitchens use.
Ounces, pounds and sticks of butter become grams.
Oven temperatures change scale, to the setting an oven dial has: 350°F becomes 180°C.
Choose US measures to go the other way: grams become cups and spoons, milliliters become cups, and Celsius becomes Fahrenheit.
Why a cup is not one weight
Most converters turn every cup into the same number of grams. That is only right for water. A cup of each of these weighs something different, which is why the converter looks at the ingredient before it writes a weight.
| Ingredient | ½ cup | 1 cup |
|---|---|---|
| All-purpose flour | 60 g | 120 g |
| Granulated sugar | 99 g | 198 g |
| Brown sugar (packed) | 107 g | 213 g |
| Powdered sugar (unsifted) | 57 g | 113 g |
| Butter | 113 g | 227 g |
| Honey | 168 g | 336 g |
| Rolled oats | 45 g | 89 g |
| Cocoa powder | 42 g | 84 g |
| Chocolate chips | 85 g | 170 g |
| Rice (uncooked) | 99 g | 198 g |
When a line names an ingredient the converter has no weight for, it does not guess. A cup becomes 240 ml, which is always true, and you can weigh it yourself.
What stays as it is
Teaspoons and tablespoons. Metric recipes use them too, as 5 ml and 15 ml.
Counted things: 2 eggs, 3 cloves of garlic, 1 onion.
Lines with no amount, such as salt to taste.
Lines the converter left alone are shown in a lighter color, so you can see at a glance what changed.
Where the weights come from
Ingredient weights come from King Arthur Baking’s ingredient weight chart and from USDA FoodData Central, checked in November 2026. Oven settings follow the pairs printed on oven dials and in the oven temperature converter.
