Convert Fahrenheit to Celsius










-1















I need some help for an web app I make for a school pjoject.
I want to convert the temperature from Fahrenheit to celsius.



Now I wrote this code:



$("#desc").html('Sky: ' + data.weather[0].description);


var fahr = data.main.temp + " °F";
var cels = ("fahr" - 32) * 5 / 9 + " °C";

$("#temp").html(data.main.temp + " °F");

$("#celButt").on("click", function()
$("#temp").html(cels););

$("#fahrButt").on("click", function()
$("#temp").html(fahr););


If I click te button to convert the data I get this as result:



NaN °C



Someone who can help me?



Thanks!!

    Change ("fahr" - 32) * 5 / 9 + " °C" to (data.main.temp - 32) * 5 / 9 + " °C". Don't know what you were trying to do by subtracting a number from a string!

    I don't understand why there is string ("fahr" - 32)

You cannot add or subtract or divide or multiply a string, which, by the time you try to calculate Celsius, is exactly what you are doing.



You are trying to subtract the number 32 from the string "80 °F" for example, which doesn't make sense.



Instead, you can do the following :



var fahr = data.main.temp + " °F";
var cels = (data.main.temp - 32) * 5 / 9 + " °C";


Also you may as well change :



 $("#temp").html(data.main.temp + " °F");


To



 $("#temp").html(fahr);


For increased readability and to keep things consistent.
