A few useful details
Swap units keeps the amount you entered. Choose another measurement type to keep a separate amount for it.
Results use exact unit definitions and are rounded only for display. The ≈ symbol means the displayed number is rounded. More digits do not make a measurement more accurate. Scientific notation such as 1e+12 means 1 trillion.
Enter up to 12 decimal places, with an absolute value no larger than 1 trillion. Use zero or positive amounts except for temperatures. Spaces, thousands separators, fractions and scientific-notation input are not accepted.
Volume does not convert to weight: the result would depend on the material. Kitchen measures vary by country; check the unit on your recipe. For everyday use, not medical dosing or safety-critical work.
