Cooking Unit Converter

How this tool works

Choose two units of the same type: volume, mass or temperature. The tool distinguishes a US customary cup from a 250 millilitre metric cup. Tablespoons and teaspoons here use US customary definitions. Ounces measure mass, while US fluid ounces measure volume. Converting cups of flour into grams requires the ingredient’s density and packing method, so cross-type conversions are deliberately rejected. Temperature supports Celsius, Fahrenheit and Kelvin. Rounded results are suitable for comparison, while kitchen measuring techniques introduce additional variation.

How many grams are in a cup?

It depends on the ingredient: a cup of flour weighs far less than a cup of sugar or water. Convert by ingredient, or weigh ingredients for the most accurate results.

Are US and UK cups the same?

No. A US cup is about 237 ml, a metric cup is 250 ml, and older UK recipes may use a different cup. Check which one your recipe means.

How many teaspoons are in a tablespoon?

Three teaspoons make one tablespoon in US and metric measures. Australian tablespoons are larger, at 20 ml.

How do I get a useful result?

Start by reading the field labels and the method above. Replace the example values with information that matches your own situation, then use the main button to generate the result. Review the units, dates and any assumptions before copying or printing it. If you change an input, run the tool again so the output reflects your latest choices. An example is a starting point for learning the controls, not a recommendation for your circumstances.

Does this page upload my information?

This tool performs its work in your browser. Its input values are not submitted to a server by the calculator. Closing or reloading the page clears unsaved work. Checklist pages offer an explicit browser-save option; that storage belongs to this browser and device and may be cleared by private browsing or browser settings. Downloads, printed pages and copied text contain whatever information you included, so keep them somewhere appropriate.

Can I use it on a phone?

The form and result panels adapt to a smaller screen. Use your device’s normal keyboard to enter values, and review the output before sharing it. The print button opens the browser’s print controls, where available. Printing and saving as PDF depend on your operating system. If a feature is unavailable, try a current browser with JavaScript enabled. Keep a separate copy of anything important; the page is not a cloud backup service.
