About the Temperature Converter

Temperature Converter maps the source through Celsius and applies the correct offset and scale for Fahrenheit or Kelvin. It rejects physically impossible values below absolute zero.

How to use the Temperature Converter

  1. Enter the temperature value.
  2. Select the source and destination scales.
  3. Convert and keep the target unit attached to the result.

Practical tips

  • Kelvin is written without a degree symbol.
  • A temperature difference converts differently from an absolute temperature because offsets cancel.
