Cooking & Baking Converter

Convert cups, tablespoons, teaspoons, grams, ounces, pounds and milliliters for cooking and baking. Pick an ingredient — flour, sugar or butter — for a weight conversion that actually matches what is in your bowl.

How We Get These Weights

Gram weights per cup come from a published reference, not a guess.

Cups measure volume, but grams measure weight — so a gram figure for flour, sugar or butter depends on that ingredient's density. The per-cup weights used here (flour, granulated sugar, brown sugar, powdered sugar and butter) come from the King Arthur Baking ingredient weight chart, a widely cited baking reference. Water and other pourable liquids use the physics-based 1 gram per milliliter instead, since that conversion needs no reference table.

Frequently Asked Questions

How many grams are in a cup of flour?
One cup of all-purpose flour weighs about 120 grams, using King Arthur Baking's ingredient weight chart. Flour packs differently depending on how it is scooped, so 120 g is a practical baking average rather than a fixed physical constant — spoon the flour into the cup and level it off to get closest to that weight.
How many tablespoons are in a cup?
There are 16 tablespoons in 1 US cup, and 3 teaspoons in 1 tablespoon. These are fixed volume ratios that hold for any ingredient, unlike gram conversions, which depend on how dense the ingredient is.
How much does a stick of butter weigh in grams?
A standard US stick of butter is half a cup by volume, which weighs about 113 grams. That comes from King Arthur Baking's figure of 227 grams per cup of butter, halved for one stick.
Why do cups and grams need an ingredient to convert accurately?
Cups measure volume and grams measure weight, so converting between them depends on the ingredient's density. A cup of flour weighs less than a cup of sugar, and both weigh less than a cup of butter, so picking the right ingredient in the dropdown gives an accurate gram figure instead of a generic guess.
