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 \(32\).
or
For example: Convert 30 °C into °F
\(F = C × 9/5 + 32 F\)
\(F = C × 9/5 + 32 F\)
\(= (30 × 9/5) +32 F\)
\(= (270/5) +32F\)
\(= 54 + 32F\)
\(= 86 °F\)
Conversion of Celsius º\(C\) to Kelvin \(K\):
We convert Celsius to Kelvin by adding (\(273\)) to the Celsius of temperature.
For example: Convert \(100 °C\) into Kelvin
\(K = °C + 273K\)
\(K = °C + 273K\)
\(= 100 + 273 K\)
\(=373K\)
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,
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,
Conversion of Kelvin \(K\) to Celsius º\(C\):
We convert Kelvin to Celsius by subtracting (273) from the temperature in Kelvin.
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,
