For recipes in cups, the cups to grams calculator converts 55 ingredients, with dedicated pages for flour and sugar. If your recipe is in grams, use the grams to cups calculator. Butter has its own converter for sticks, tablespoons and 250 g blocks.
For liquids and spoons, use the cups to ml converter, the cups to ounces converter (which explains fluid versus weight ounces), cups to tablespoons and the tablespoons to ml converter.
For the oven, convert °F, °C and gas mark, and plan a turkey with USDA roasting and thawing times. Check any meat against the safe cooking temperature chart.

Frequently asked questions
Why do recipes from different countries use different cups?
The US cup is 236.6 ml (8 US fluid ounces), while the UK, Canada, Australia and New Zealand use a metric cup of 250 ml. Australia also has a 20 ml tablespoon, against 15 ml elsewhere. The tools let you choose the system, and they default from your region.
Is a cup a measure of weight or volume?
Volume. A cup of flour weighs about 120 g and a cup of honey about 336 g, so converting cups to grams needs the ingredient. The cups to grams calculator covers 55 of them.
Which weights do the calculators use?
King Arthur Baking's ingredient weight chart for most dry ingredients and USDA FoodData Central for liquids, with the other source shown for comparison so you can see the spread.
Should I bake by weight instead of cups?
Yes where possible. A cup of flour can vary by 15 to 20% depending on how it is scooped, while a scale gives the same result every time.
Are the food safety temperatures official?
They follow USDA and FoodSafety.gov minimum internal temperatures, such as 165°F for poultry and 145°F for whole cuts of beef and pork. They are general guidance, and a food thermometer is the only reliable check.
Do the oven conversions work for fan ovens?
The oven converter shows a fan setting about 20°C lower than a conventional oven, which is the usual guideline. Ovens vary, so check your manual and use an oven thermometer.
