Change PHP code for Joomla Module

Question

I am slowly getting my head around PHP but being self taught, it is taking a while :p

Anyway... I have installed the SP Weather module but have come across a problem. I would like to display the wind speed in MPH but the temperature in celcius.

The module only allows you to select imperial or metric for all settings so I can't, without editing the code, adapt it to do what I want it to do.

I've had a look in the code but need some help. Does anyone know how I can do this? Code is below.

Kind regards

It looks like this is because the unit parameter is actually passed to the web service (Yahoo?) that is used to get the data. You might want to just do the conversion yourself.

echo JText::_($data['wind']['direction']) . JText::_('SP_WEATHER_AT') . $helper->Numeric2Lang($data['wind']['speed']) . ' ' . JText::_(strtoupper($data['units']['speed'])); ?></div>

Is the line you need to edit I think. Replace "' ' . JText::_(strtoupper($data['units']['speed']))" with ' MPH' to print your unit. Then replace "$data['wind']['speed']" with "round($data['wind']['speed']/1.6)".

Now if you set it to celsius it should show speed in mph. Not tested so typos in code are likely, but the idea should work.
