Temperature Conversion:
Temperatures between scales can be converted using the following equations.
 
Conversion of Celsius (º\(C\)) to Fahrenheit º\(F\):
  
The temperature (\(T\)) in degree Fahrenheit (\(ºF\)) is equal to the temperature (\(T\)) in degree Celsius (\(ºC\)) multiplied by \(9/5\), and plus \(32\).
 
°F=1.8×°C+ 32
 
or
 
°F=95×°C+ 32
 
For example: Convert 30 °C into °F
 
\(F = C × 9/5 + 32 F\)
 
\(= (30 × 9/5) +32 F\)
 
\(= (270/5) +32F\)
 
\(= 54 + 32F\)
 
\(= 86 °F\)
 
Conversion of Celsius º\(C\) to Kelvin \(K\):
  
We convert Celsius to Kelvin by adding (\(273\)) to the Celsius of temperature.
 
K=273.15+ºC
 
For example: Convert \(100 °C\) into Kelvin
 
\(K = °C + 273K\)
 
\(= 100 + 273 K\)
 
\(=373K\)
 
Conversion of Fahrenheit  º\(F\) to Celsius  º\(C\):
 
The formula to convert temperature \(T\) in degrees Fahrenheit (\(ºF\)) to the temperature (\(T\)) in Celsius is, 
 
°C=°F32×59
 
Conversion of Fahrenheit  º\(F\) to Kelvin \(K\):
  
The formula to convert temperature \(T\) in degrees Fahrenheit (\(ºF\)) to the temperature (\(T\)) in Kelvin is, 
 
K=°F32×59+273.15
 
Conversion of  Kelvin \(K\) to Celsius º\(C\):
 
We convert Kelvin to Celsius by subtracting (273) from the temperature in Kelvin.
 
ºC=K273.15
 
Conversion of  Kelvin \(K\) to Fahrenheit º\(F\):
 
The formula to convert temperature \(T\) in Kelvin to the temperature (\(T\)) in degrees Fahrenheit (\(ºF\)) is, 
 
°F=K273.15×95+32
 
The relationships between the three common temperature scales are shown in below figure.
