Temperature Conversion Instructions

Enter a value for any one of the three temperature scales and the others will
automatically be calculated. Javascript must be enabled in your web browser for
calculations to occur.

Significant figures are used. Results are shown only with as many significant
figures as the quantity that was entered. Scientific notation may be used for
large results or if the number of significant digits would be ambiguous otherwise.
The calculator follows proper rounding rules for scientific purposes.

The formulas used to convert between temperatures are as follows:

  • °C = (°F – 32) * 5 / 9
  • °F = (°C * 1.8) + 32
  • K = °C + 273.15
  • °C = K – 273.15

About Temperature Conversion

The fahrenheit was proposed by Daniel Gabriel Fahrenheit. The scale is often mispelled as “farhenheit”, “farenheit”, “farhenhiet”, or “farenhiet”.

The Celcius scale is still sometimes called the “centigrade” scale because it is divided into 100 divisions. It was devised by Andres Celsius.
