These converters use fixed mathematical factors for length, mass, area, and US liquid volume, plus the required offset for Celsius and Fahrenheit. Area factors are squared length factors, and a US liquid gallon is different from an imperial gallon.

- Confirm whether a volume uses US liquid gallons or imperial gallons before converting.
- Use the reverse converter when you need to preserve the direction and units in a saved result.
