Frequently asked questions
How do I convert grams to cups?
Use the Grams to Cups Calculator: pick the ingredient, because a cup of flour weighs less than a cup of sugar, enter the amount and read the result in cups, tablespoons and teaspoons.
How do I convert Celsius to Fahrenheit or inches to centimeters?
Use the Temperature Converter for Celsius, Fahrenheit and Kelvin, or the Length Converter for millimeters, centimeters, meters, inches and feet. Each shows the formula behind the result.
Why does a cup of flour weigh less than a cup of sugar?
Cups measure volume, grams measure weight, and ingredients differ in density. That is why the Grams to Cups Calculator asks you to pick the ingredient first.
Do these calculators store my numbers?
No. Every calculation runs in your browser and nothing you enter is saved or uploaded.
