How it works
Each category has a reference unit. Values are converted to that reference and then to the target unit. Temperature is special because its scales have different zero points, so dedicated formulas are used.
Frequently asked questions
Are the conversion factors exact?
Yes - standard SI definitions such as 1 inch = 25.4 mm are used, so results match reference tables.
What data storage convention do you use?
Binary units, where 1 KB = 1024 bytes - the convention used by most operating systems.
