                     Temperatures in Space
                               

Much of space is very cold -- as low as three degrees Kelvin,  but stars are very hot.
Because the temperature extremes are so much wider than earth's, astronomers use the Kelvin scale.


We are used to measuring temperatures in Celsius (which is the same as Centigrade) or Fahrenheit degrees.

Temperatures in space are measured in degrees Kelvin.

Try doing some temperature conversions yourself

Fahrenheit: Celsius:   Kelvin:  

 

     
Temperature Conversion Formulas
Celsius and Kelvin Kelvin = Celsius + 273.15 Celsius = Kelvin - 273.15
Celsius and Fahrenheit Celsius = 5/9 x (Fahrenheit -32) Fahrenheit =( Celsius/(5/9)) + 32
