How can I convert Fahrenheit to Celsius in Stormy Android app?

Currently temperature is being displayed in Fahrenheit. I want to display in Celsius instead. How can I achieve this?

Mine's a little modified for getting location from GPS but you should be able to follow it.

    protected String getForecastUrl(double latitude, double longitude) {
        return "https://api.forecast.io/forecast/" + ApiKey.getApiKey() +
                "/" + latitude + "," + longitude +
                "?units=si";
    }

I changed my getTemperature() & getTemperatureMax() methods to calculate the conversion:

    public int getTemperatureMax() {
        Double celsius = (mTemperatureMax - 32.0) * 0.5555;
        return (int) Math.round(celsius);
    } 

    public int getTemperature() {
        double celsius = (mTemperature - 32.0) * 0.5555;
        return (int)Math.round(celsius);
    }

Do that in each of the classes where the method exists. There's probably a nicer way of doing that, rather than having it in three classes, but I let that slide for now!

I hope that helps.

It worked for me. But did you tried appending URL to do so?

I changed my version to show Celsius too.

Let me dig my code up and I'll post right back!

You can also have forecast.io return Celsius directly by appending "?units=si" to the request URL (or "?units=auto" to choose units based on location).

I tried appending the URL but it didn't work. Can you tell me the code-snippet please?
