How the conversion works

The input is converted into K using the source factor and offset, then into Fahrenheit. This keeps unit definitions consistent across the temperature collection.

Factors are maintained in the versioned unit dataset. Output is rounded to your selected significant digits; calculation uses JavaScript double precision.
