How it works
Convert to Kelvin, then to the destination scale: K = °C + 273.15; °F = °C × 9/5 + 32.

Common questions
Is a temperature reading converted the same way as a temperature difference?
No. Readings such as Celsius to Fahrenheit need an offset as well as a scale factor. Temperature differences use the scale factor alone; use the separate temperature interval tool.
Why can a converted result differ in its last digits?
Display rounding and approximate measured unit factors can affect the final digits. Select more decimal places when available, and check that both tools use the same unit definition.
