About the Cooking Measurement Converter
Cooking Measurement Converter changes recipe amounts between the units used in different countries. Choose an ingredient such as flour, sugar, butter, honey, milk or rice, enter an amount and pick the units to convert from and to: US cups, metric cups, tablespoons, teaspoons, fluid ounces, millilitres, litres, grams, kilograms, ounces or pounds. Because a cup of flour weighs far less than a cup of honey, the tool uses the typical weight of each ingredient when you cross between volume and weight, and it tells you when it is doing so. Results also show the amount as a kitchen fraction such as 3/4 cup. A second panel converts oven temperatures between Celsius, Fahrenheit, fan settings and gas marks. Everything runs in your browser.

How to use the Cooking Measurement Converter
- 1Choose the ingredient. It matters when you change between cups or spoons and grams.
- 2Type the amount and choose the unit to convert from and the unit to convert to.
- 3Read the result and the nearest kitchen fraction, and check the other units shown below it.
- 4For oven temperatures, pick °C or °F, type the temperature and read Celsius, Fahrenheit, fan and gas mark.
- 5Use the copy button to keep the result.
Why recipes use different units
American recipes measure most ingredients by volume, in cups and spoons, while much of the rest of the world weighs them in grams. That is easy to handle for water and milk, since a millilitre of water weighs about a gram, but it is a problem for dry ingredients. A cup can hold very different weights depending on the ingredient and on how tightly it is packed.
This converter keeps a list of typical weights per US cup for common ingredients. When you switch between a volume and a weight, it uses the ingredient you selected, and shows a note so you know the result is an estimate.
Getting good results in baking
- Weigh flour and sugar if you can. Grams are the same everywhere.
- If you use cups, spoon flour into the cup and level it with a knife, without pressing.
- Pack brown sugar into the cup, as recipes assume.
- Use the same set of measuring spoons and cups all through a recipe.
- Check whether the recipe means a US cup, a metric cup or a mug.
Oven temperatures
Recipes give oven temperatures in Celsius, Fahrenheit or gas marks, depending on where they were written. The converter changes between them and adds an approximate setting for a fan oven, which is usually 20 °C lower than the conventional setting. Gas marks are steps rather than exact temperatures, so the tool shows the nearest mark.
Every oven runs a little differently. An inexpensive oven thermometer is a good way to find out whether yours is too hot or too cold, and to correct recipes accordingly.

Frequently asked questions
How many grams are in a cup of flour?
A US cup of all-purpose flour is usually given as 120 to 125 grams, and this tool uses 125. Bread flour is about 127 grams, whole wheat about 120 and cake flour about 114. The real amount depends on whether you spoon and level the flour or scoop it straight from the bag, which can add 20 percent.
Why does a cup of different ingredients weigh different amounts?
A cup measures volume, the space something takes up, while grams measure weight. Flour is light and airy, sugar is denser, and honey is much heavier than either. That is why a cup of honey is about 340 grams and a cup of flour only about 125 grams.
How many tablespoons are in a cup?
A US cup holds 16 tablespoons or 48 teaspoons, and a tablespoon is about 14.8 millilitres. A metric cup is 250 millilitres, which is close but not identical to the US cup of 236.6 millilitres.
Is a UK cup the same as a US cup?
Not quite. The US cup is 236.6 millilitres. Metric cups used in Australia, New Zealand, Canada and many modern UK recipes are 250 millilitres. Older UK recipes may use a 284 millilitre cup, which is not included here. Check which one your recipe means.
What is gas mark 4 in Celsius and Fahrenheit?
Gas mark 4 is 180 °C or 350 °F, the temperature of most standard cake and biscuit recipes. Gas mark 6 is 200 °C or 400 °F, and gas mark 1 is 140 °C or 275 °F. The table under the oven converter lists all of them.
How do I adjust the temperature for a fan oven?
A fan oven circulates hot air and cooks faster, so reduce the temperature in a recipe written for a conventional oven by about 20 °C, or 25 °F. The tool shows this as Fan oven. Check the food towards the end, because ovens differ.
Are the results exact?
Volume to volume and weight to weight conversions are exact. Cups to grams is an estimate based on typical values, since ingredients differ by brand, moisture and packing. For baking, a kitchen scale is more reliable than cups.
