FAQ
Can units from different categories be mixed?
No. Each conversion stays inside the selected category and uses one base unit.
Which volume units are used?
Volume uses US customary units and the labels say US. Imperial pints and gallons are not used.
What does the precision setting change?
The result is rounded to 2, 4, 6, or 8 decimal places. An invalid number is not converted.
