About this calculator

This celsius converter converts Celsius to Fahrenheit, Kelvin, Rankine, Delisle, Newton, Réaumur, and Rømer in one view.

Formula notes

Each scale uses its standard conversion from Celsius: F = 9/5C + 32, K = C + 273.15, R = 9/5C + 491.67, and so on.

Worked examples

  1. Example: 100°C equals 212°F and 373.15 K.
  2. A human body temperature of 37°C is 98.6°F.

How to use it

  1. Enter a temperature in any supported scale.
  2. Read the equivalent values in all other scales immediately.
  3. Clear the field to enter another temperature.

Frequently asked questions

Which scale should I enter from?

Any of them. The converter treats the value you enter as the active input and derives all other scales.

What is absolute zero in Celsius?

Absolute zero is -273.15°C, which is 0 K or 0°R on the Rankine scale.

Limits and interpretation

  • Conversions use exact scale definitions, but displayed values may be rounded.
  • Very low or high temperatures can be entered; the converter does not evaluate whether they are physically plausible for a use case.
