Is there a weather widget for android phones capable of displaying the current temperature both in Fahrenheit and Celsius at the same time? That is, I'm not looking for widgets like the one shipped with the HTC one, the AccuWeather app etc. which only seem able to display the temperature in one scale at a time.
Edit 2014: I currently run Android 4.4.2, so that'd be a good cut-off. It doesn't have to be fancy. Ideally, it'd be like the HTC One (M7) widget which shows the time, a symbol for the current weather and the temperature. The app is preferably free, but I would consider a budget up to $10 (especially if there are other interesting features).
Edit 2022: Since it appears the "Weather Notification" app by Denis Nelubin is no longer available on Google Play, alternatives for more recent versions of Android (say 10 and above) meeting the same qualifications would be very welcome.
