What this tool does

Convert a temperature reading between Celsius, Fahrenheit and kelvin. The calculation first converts the entered reading to kelvin: Celsius + 273.15, or (Fahrenheit + 459.67) × 5/9. Celsius is K − 273.15 and Fahrenheit is Celsius × 9/5 + 32. Converted fields display two decimal places. These are temperature readings with offsets, not temperature differences.

How to use Temperature Converter

  1. Prepare the input. Enter a value in the correctly labelled temperature field.
  2. Run or configure the tool. Read the automatically updated other scales.
  3. Check and use the output. Check the physical range and avoid converting a temperature difference as a reading.

How this tool works

The calculation first converts the entered reading to kelvin: Celsius + 273.15, or (Fahrenheit + 459.67) × 5/9. Celsius is K − 273.15 and Fahrenheit is Celsius × 9/5 + 32. Converted fields display two decimal places. These are temperature readings with offsets, not temperature differences.

Worked example

Input: Celsius 0

Output: Fahrenheit 32.00; kelvin 273.15.

Limits, assumptions and interpretation

Kelvin is written K without a degree sign.

  • Inputs must be finite and at or above absolute zero: −273.15 °C, −459.67 °F or 0 K. Values below those limits are rejected.
  • A temperature interval needs different rules: a 1 °C change is a 1 K change, not 274.15 K.
  • The rounded output is not instrument calibration or a statement of measurement accuracy.
