A finction to perform the coversion should be invoked after the teperature to be converted is enterd and the ENTER keyis pressed on the textbox.

To convertdegrees fahrenhiet to degrees celsius, use this formula:
CELSIUS= ( 5 / 9 ) * ( Fahrenhiet - 32 )

To covert from degrees celsius to degrees fahrenhiet, use this formula:
FAHRENHIET = ( 9 / 5 ) * ( CELCIUS + 32 )
