[CJ Grucza]

I am able to convert fahrenheit to celsius but i am having a problem with converting celsius to fahrenheit. Why?

[Walter Roberson]

We don't know given that little information.

T*9/5+32

Answer 1

[Amit]

disp('This program convert Celsius to Fahrenheit');
Celsius=input('Write a temperature in Celsius and you''ll have the result in Fahrenheit: ');
disp([ 'x = ' num2str(Celsius) ' Celcius and y = ' num2str(Celsius*1.8+32) ' Fahrenheit'])

[Amit]

For both cases:

disp('This program convert Celsius to Fahrenheit');
val = input('Type 1 for Celcius to Farenheit and Type 2 for vice versa: ');
switch val
    case 1
        Celsius=input('Write a temperature in Celsius and you''ll have the result in Fahrenheit: ');
        disp([ 'x = ' num2str(Celsius) ' Celcius and y = ' num2str(Celsius*1.8+32) ' Fahrenheit']);
    case 2
        Faren=input('Write a temperature in Farenheit and you''ll have the result in Celcius: ');
        disp([ 'x = ' num2str(Faren) ' Fahrenheit and y = ' num2str((Faren-32)/1.8) ' Celcius ' ]);
end

Answer 2

[Diego]

function [y] = farenheit(C) 
y = 9/5 *C + 32;

%farenheit is the name of the file

@Diego is on the right track. Instead of harrassing the user for all inputs interactively, just write a basic function that can be used programmatically. Besides the exercise in writing functions, this is just a simple linear transformation.

C = [-40 0 100 1000];
F = ctof(C)

F = 1×4

-40 32 212 1832

C1 = ftoc(F)

C1 = 1×4

-40 0 100 1000
