Measurement notes
Kitchen conversions are safest when source and target units describe the same physical quantity. Volume-to-volume and mass-to-mass conversions use fixed factors, so this page can give a direct result without asking what ingredient you are measuring.
Weight-to-volume conversions are different. A cup of flour and a cup of honey do not weigh the same amount, so a generic grams-to-cups formula would be misleading. This site only publishes those conversions when the ingredient or density assumption can be stated clearly.
For practical cooking, rounded measuring tools may be less precise than the mathematical result. Use the displayed number as a conversion reference, then round appropriately for the recipe and measuring equipment you have.
US customary, Imperial, and metric units can share similar names but use different definitions. Check the labels on your recipe and measuring tools when precision matters, especially for cups and fluid ounces.
Frequently asked questions
How do I convert tbsp to mL?
