Cooking Measurement Converter
Handles cups, grams, tablespoons, teaspoons, milliliters, and ounces — with weights adjusted per ingredient. Flour and sugar don't weigh the same (125g vs 200g per cup), so we skipped the generic conversion approach entirely.

The idea for this converter came from a problem we kept running into: generic kitchen converters treat every ingredient like water. Type "one cup of almond flour in grams" and most of them spit out 240 grams — the density of water — when the USDA FoodData Central database lists almond flour at just 96 grams per cup. That is less than half, and using the wrong number turns macaron shells into crunchy little discs. The real-world density spread across common baking staples is enormous: granulated sugar packs at 200 grams per cup according to USDA FoodData Central, all-purpose flour at 125 grams, cocoa powder at just 86 grams, and honey at a whopping 340 grams. That range — 86 to 340 grams for a single cup measure — means relying on the water-density shortcut introduces anywhere from 15 to 65 percent error depending on the ingredient, which is the kind of gap that quietly wrecks recipes without the cook ever understanding what went wrong.
King Arthur Baking's ingredient weight chart lists all-purpose flour at 120 grams per cup, and even that single number hides a range — scooping from the bag versus spooning into the cup can shift the weight by 20 to 30 grams depending on technique. We built this converter around USDA FoodData Central's density values for 50-plus common cooking ingredients, so whether you are measuring cocoa powder, honey, or rolled oats, you get the accurate gram weight based on real measured data rather than a water-based guess.
Common Conversions at a Glance
- 1 cup all-purpose flour = 125 grams
- 1 cup granulated sugar = 200 grams
- 1 cup butter = 227 grams (2 sticks)
- 1 cup honey = 340 grams
- 1 cup rolled oats = 90 grams
- 1 tablespoon = 3 teaspoons = ~15 ml
- 16 tablespoons = 1 cup
Measuring Tips for Better Baking
- 1. Spoon flour into your cup and level it off — scooping directly from the bag packs it down and adds up to 30% extra weight.
- 2. Brown sugar needs firm packing to measure right. Press it down into the cup.
- 3. For liquids, use a spouted measuring cup and check at eye level.
- 4. A quick swipe of oil inside the cup makes sticky stuff like honey slide right out.
Frequently Asked Questions
How many grams in a cup?
It depends on the ingredient. A cup of water weighs 237g, a cup of flour weighs 125g, and a cup of sugar weighs 200g. Always use ingredient-specific conversions for accurate results.
Why does 1 cup of flour weigh less than 1 cup of sugar?
Flour is less dense than sugar. Flour particles are irregularly shaped and trap air, while sugar granules pack more tightly. This is why weight-based measuring is more accurate than volume.
How many tablespoons in a cup?
There are exactly 16 tablespoons in 1 US cup. Each tablespoon equals 3 teaspoons, so 1 cup = 48 teaspoons.
Is a US cup the same as a metric cup?
No. A US cup is 236.588 ml, while a metric cup (used in Australia and some other countries) is 250 ml. Our converter uses US cups by default.
Can I use this converter for cooking and baking?
Yes. The converter works for both cooking and baking. For baking, selecting the specific ingredient gives you much better accuracy than generic volume conversions.
How accurate are these conversions?
Our density data comes from USDA FoodData Central and established baking references like King Arthur Flour. The values are accurate for typical measuring conditions.
