Above are two links that show you the HTML form and PHP code for Fahrenheit/Celsius Temperature Conversion.

Below are two examples of the working of Maths problems Fahrenheit/Celsius.

*How many degrees Celsius are 68 degrees Fahrenheit?*

Replace Fahrenheit with 68 and solve for Celsius:

C = (68 - 32) * 5/9,

C = 36 * 5/9,

C = 20

20 °C = 68 °F

*At what temperature are Celsius and Fahrenheit temperatures equal?*

Replace both temperatures with "T" in one of the equations above and just solve for T:

T = T * 9/5 + 32,

-32 + T = T * 9/5,

-32 = T * 4/5,

-40 = T

-40 °C = -40 °F
