KDE-Forum.org

I just came in from the patio after having my laptop overheat because I was sitting in the sun. After finishing blowing out the dust from the heat vents, I thought I'd try to find out if it is possible to show the temperature in Celsius while using the temperature widget for Plasma. I've got Kubuntu 9.04 installed with KDE 4.2. I don't see any configuration setting to do this.

I'm accustomed to seeing temperature readings in Celsius and prefer the metric system anyways. Are there any other widgets that give the readout in Celsius, or a way to change the built-in widget?
