Cant get temperature in celsius

Question

I know this type of questions are asked before...but i cant figure it out...i have read this OS questions link1 and link2

Well i am developing a weather forecast app and for that i am using yahoo weather api.

I am using this url for response

 String url = "https://query.yahooapis.com/v1/public/yql?q=select * from weather.forecast where woeid="+woeid+
                " and u='c'&format=xml&env=store://datatables.org/alltableswithkeys";

        url = url.replace(" ","%20");

and i am getting this response

as in response...i am not getting temp in Celsius...plese help me

just replacing spaces with "%20" might not be enough: do a proper `UrlEncode` — Cee McSharpface, Mar 25 '16 at 12:52
difficult to reproduce, the call returns a http response 400 most of the time: on https://developer.yahoo.com/weather they say that the public endpoint you're using, https://query.yahooapis.com/v1/public, has been deprecated as of March 15th, 2016 and they now enforce OAuth on a different address. — Cee McSharpface, Mar 25 '16 at 16:40
the API does not work as documented, at least not for the location Ahmedabad (WOEID 2295402). The `u='c'` condition is used correctly, but results are always in Fahrenheit. I could also confirm that when testing OP's query in the YQL developer console [here](https://developer.yahoo.com/yql/console/?q=select%20*%20from%20weather.forecast%20where%20woeid%3D2295402%20and%20u%3D'c'&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys), same with the code from the accepted answer of [this](http://stackoverflow.com/questions/21092164/yahoo-weather-api-celsius?lq=1) — Cee McSharpface, Mar 25 '16 at 21:12
Also had the same problems a few days ago, but now it shows celsius correctly. It's also a bit unstable, so I think @dlatikay is onto something, and that it may be related to the enforcement of OAuth. — janlindso, Mar 26 '16 at 03:40

EDIT

I was trying your location on the console and you get Celsius in the forecast and current conditions if you request those items. I tried:

select item.forecast from weather.forecast where woeid = 2295402 and u='c'

that returned a 10-day forecast in Celsius. The URL would be

https://query.yahooapis.com/v1/public/yql?q=select%20item.forecast%20from%20weather.forecast%20where%20woeid%20%3D%202295402%20and%20u%3D'c'&format=xml&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

Changing item.forecast to item.conditions does the same with the current conditions. I tried again select * and it gives the Fahrenheit error. Perhaps using separate queries for those items could help you?

It seems the return temperature is in Fahrenheit.

You can convert this to Celsius using the following formula:

C = (F-32) x 5/9
