Temperature converter

(requires JavaScript)

...because sometimes even perfectly reasonable and intelligent people can't be bothered to do trivial arithmetic.

The form below will convert a temperature to/from the temperature units of your choice. To use it, enter the temperature into the appropriate field below, then hit the Tab key or click somewhere outside that field. The remaining two fields will update automatically.

Conversion formulas

To degrees Centigrade:

$T_{^\circ\mathrm C}\qquad=\qquad\frac{5}{9}\,\left(T_{^\circ \mathrm F}-32\right)\qquad=\qquad T_{\mathrm K}-273$

To degrees Fahrenheit:

$T_{^\circ\mathrm F}\qquad=\qquad\frac{9}{5}\,T_{^\circ\mathrm C}+32\qquad=\qquad\frac{9}{5}\,\left(T_{\mathrm K}-273\right)+32$

To Kelvin:

$T_{\mathrm K}\qquad=\qquad T_{^\circ\mathrm C}+273\qquad=\qquad\frac{5}{9}\,\left(T_{^\circ\mathrm F}-32\right)+273$
