Cooking Measurement Converter
Convert between the US kitchen measurements you meet in recipes — cups, tablespoons, teaspoons, fluid ounces and milliliters — plus weight in grams and ounces. A dedicated cup-to-grams tab handles common ingredients like sugar, flour, butter and water, so a recipe in ounces or cups scales perfectly. Fast, accurate and private.
What is a cooking measurement converter?
A cooking measurement converter is a tool that turns a kitchen measurement from one unit into another so you can follow any recipe with the tools you own. American recipes usually measure volume — cups, tablespoons and teaspoons — while European and professional recipes weigh ingredients in grams and ounces. Because a cup of one ingredient does not weigh the same as a cup of another, converting between volume and weight needs a density factor. This converter handles that for you.
Volume conversions are exact and simple: 1 US cup is 236.588 mL, 1 tablespoon is 14.787 mL, 1 teaspoon is 4.929 mL and 1 fluid ounce is 29.574 mL. Weight conversions are also exact, with 1 ounce equal to 28.3495 grams. The tricky part is the cup-to-grams tab, where the same volume produces different weights: a cup of granulated sugar is about 200 grams, but a cup of all-purpose flour is only about 125 grams because flour is lighter and fluffier. Butter sits between the two at about 227 grams per cup, while a cup of water weighs 236.588 grams. This tool uses those standard US densities so your baking comes out right every time.
How to use
- Pick a tab: Volume, Weight, or Cups to grams.
- Enter a value, then choose the unit you are converting from and the unit you want.
- On the Cups to grams tab, also select the ingredient — sugar, flour, butter or water.
- Click Convert and read your result instantly.
Example
On the Volume tab, enter 2 with From set to Cups and To set to Milliliters — the result is 473.18 mL. Switch to Cups to grams, enter 1 cup of all-purpose flour and the converter gives 125 grams (about 4.4 oz). Choose sugar instead and the same cup returns 200 grams, because sugar is denser than flour.
Common use cases
- Scaling a US recipe down or up when you do not have the measuring cups it calls for.
- Converting a European recipe in grams into cups and spoons for American tools.
- Replacing a listed ingredient by weight for more accurate baking results.
- Doubling or halving a recipe while keeping ingredient ratios correct.
Pro tips
- Weigh flour for the most consistent baking — a cup can vary by 10 to 20 grams with how you scoop it.
- Sugar, flour and butter have different densities, so always pick the right ingredient.
- Fluid ounces measure volume, not weight; do not confuse them with ounces of weight.
- Use a kitchen scale for accuracy, and treat a US cup as 236.588 mL for conversions.
FAQ
How many milliliters are in a cup?
One US cup is exactly 236.588 milliliters. A stick of butter is 113 grams or 8 tablespoons, and a pint has 2 cups.
How many tablespoons are in a cup?
There are 16 tablespoons in a US cup. There are also 3 teaspoons in a tablespoon, so a cup equals 48 teaspoons.
How many grams are in a cup of sugar?
One US cup of granulated sugar weighs about 200 grams. Brown sugar and powdered sugar differ, so always check the ingredient when converting.
How many grams are in a cup of flour?
One US cup of all-purpose flour weighs about 125 grams. Because flour is fluffier than sugar, the same volume weighs much less.
How do I convert cups to grams?
Multiply the volume in milliliters (1 cup = 236.588 mL) by the ingredient's density in grams per milliliter, then round to a whole number.
Is a US cup the same as a metric cup?
No. A US cup is 236.588 mL, a metric cup is 250 mL and an imperial cup is 284 mL. Use the US value for standard American recipes.
How many grams is a stick of butter?
One US stick of butter is 8 tablespoons, or half a cup, and weighs about 113 grams. A full cup of butter weighs about 227 grams.
How do I convert ounces to grams?
Multiply the ounces by 28.3495. So 8 ounces is 8 × 28.3495 = 226.8 grams, which matches one cup of butter.
How many fluid ounces are in a cup?
There are 8 fluid ounces in a US cup. Fluid ounces measure volume, not weight, so a cup of flour is still 8 fluid ounces but only about 125 grams.
Is this cooking converter free and private?
Yes. It is completely free, runs entirely in your browser, and nothing you enter is uploaded.
