Cooking measurement
converter.
Convert cups, tablespoons, millilitres, grams, ounces, pounds and oven temperatures. Use ingredient-specific density when crossing between volume and weight.
Volume / weight / oven
Convert cups, grams, ounces and oven temperatures.
Volume-to-volume and weight-to-weight conversions are direct. Cups-to-grams needs the selected ingredient because flour does not weigh the same as honey.
- US cup and spoon standards are labelled
- Ingredient-aware cups-to-grams estimates
- Celsius and Fahrenheit oven conversion
Ingredient densities are practical averages. Packing, grind, humidity and measuring technique can change the real weight.
1 US cup = 236.59 millilitres.
Popular cooking conversions
Cups to grams, grams to cups and oven temperature.
Convert cups to grams, grams to cups, ounces and oven temperatures.
The cooking measurement converter handles volume, weight and oven temperature. Teaspoons, tablespoons, US cups, millilitres, litres and US fluid ounces convert through millilitres. Grams, kilograms, ounces and pounds convert through grams. Celsius and Fahrenheit use their standard temperature formulas.
A cup is volume while a gram is weight, so crossing between them requires ingredient density. The selector provides practical average grams per millilitre for common ingredients. Those estimates are clearly labelled because flour packing, sugar crystal size, humidity and measuring technique change the real amount.
For water-like liquids, volume and weight may look nearly interchangeable because one millilitre of water is about one gram under ordinary kitchen conditions. That shortcut fails for oil, honey, flour, oats and many other ingredients. Always select the ingredient before reading a volume-to-weight result and keep the approximation note with the converted recipe.
Unit names also matter. A US tablespoon, imperial tablespoon and Australian tablespoon are not universally the same, and a metric cup is not the US cup used here. The interface spells out the basis instead of displaying an ambiguous “cup.” When the original recipe defines its own measurement standard, follow that definition over a generic converter.
Use extra precision while calculating, then round to equipment that can actually measure the result. A home scale reading to one gram cannot reliably portion 0.04 g of spice, while a production formula may require a specialised fine scale. Avoid repeated conversions because every rounding step can compound the difference.
Oven conversion changes the temperature number, not the behaviour of a particular appliance. Fan-assisted ovens often require a separate adjustment from conventional ovens, and thermostats can run hot or cool. Treat the converted setting as the recipe equivalent, then apply the manufacturer’s guidance and the doneness cues in the recipe. Use an oven thermometer when consistency matters.
How to use this tool
- Enter a numeric amountDecimals are accepted. Use the amount from the recipe before rounding.
- Choose from and to unitsKeep volume with volume or weight with weight for direct conversions. Temperature only converts to temperature.
- Select the ingredient when neededThe ingredient field appears for volume-to-weight or weight-to-volume conversion and supplies the density.
- Round for the jobKeep precision for scaling and production; use a practical spoon or scale resolution for home cooking.
Reference values used by the converter
US volume standards are used because the label says US cup, tablespoon and fluid ounce.
| Measure | Base value | Type |
|---|---|---|
| 1 US teaspoon | 4.9289 ml | Volume |
| 1 US tablespoon | 14.7868 ml | Volume |
| 1 US cup | 236.5882 ml | Volume |
| 1 ounce | 28.3495 g | Weight |
| 1 pound | 453.5924 g | Weight |
Worked example
Convert two US cups of flour to grams
Enter 2, choose Cup (US) as the source, Gram as the destination and All-purpose flour as the ingredient. The converter first turns two cups into 473.176 millilitres, then multiplies by the stored average density of 0.53 g/ml.
The displayed answer is about 250.78 g. A flour manufacturer or tested recipe may use a different cup weight because scooping and packing vary. For repeatable baking, prefer the recipe author’s stated gram value when one is available.
Formula or selection rule
Same dimension: result = amount × source base factor ÷ target base factor. Volume to weight: millilitres × ingredient density = grams. °F = °C × 9/5 + 32.
Common mistakes and browser limits
- Converting cups to grams without selecting the actual ingredient.
- Mixing US cups with metric or imperial cup assumptions.
- Rounding every intermediate value instead of the final answer.
- Using a volume cup to portion compressible flour inconsistently.
- Applying oven temperature conversion to cooking time.
FAQ
Questions people ask about this tool
How many millilitres are in a US cup?
One legal US customary cup used here is 236.5882 millilitres. Metric cups and traditional local cups can differ.
How many grams are in one cup of flour?
Using the tool’s average density, one US cup of all-purpose flour is about 125.39 grams. Real cup weight changes with packing and flour type.
Can cups be converted to grams exactly?
Only after specifying the ingredient, and even then the result is an estimate unless a tested recipe defines its own cup weight.
How do I convert Celsius to Fahrenheit?
Multiply Celsius by 9/5 and add 32. To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9.
Does the converter use US or imperial fluid ounces?
It uses US fluid ounces and labels them accordingly. Imperial fluid ounces are different.
