Fahrenheit To Celsius in VB NET

Fahrenheit To Celsius in VB.NET

 

Problem

Write a program to ask the user to give temperature in Fahrenheit and then the program will convert the given temperature into Celsius equivalent. 

Formula to convert Fahrenheit to Celsius below

 °C = (°F  -  32)  x  5/9

Example 

50°F = 10°C ( (50°F - 32) multiplied by 5/9 = 10°C )
