Converters — common questions

Should I use the general unit converter or a dedicated converter?

Use the general unit converter when switching between measurement types. Use a dedicated length, weight, or temperature converter when you want more common units for one category on screen.

Do temperature conversions use simple multiplication?

No. Celsius, Fahrenheit, and Kelvin have different zero points, so temperature conversions use offset formulas rather than only multiplying by a factor.
