I need help with this question. I need it in HTML5 format.

Implement the following functions: (a) Function Celsius returns the Celsius equivalent of a Fahrenheit temperature, using the calcuation: C = 5.0 / 9.0 * (F-32); (b) Function fahrenheit returns the Fahrenheit equvalent of a Celsius temperature, using the calculation F = 9.0/5.0 * C +32; (c) Use these functions to write a script that enables the user to enter eigher a Fahrenheit or a Celsius temperature and displays the Celsius or Fahrenheit equivalent. Your HTML5 document should contain two buttons -- one to initiate the conversion from Fahrenheit to Celsius and one to initiate the conversion from Celsius to Fahrenheit. Here is what the output should look like.
