Understanding your result
The converted value describes the same volume quantity in the selected target unit. Display rounding does not add precision to the original measurement.
Common mistakes
- Confusing the source and target units, or overlooking a prefix or case-sensitive symbol.
- Mixing US and imperial gallons or treating every recipe cup as the same volume.
Check your calculation
