Unit conversion tools not working?

You can also try a reboot. This is an issue I don't think anyone has seen or reported before. To do a reboot, hold down the ON key, and while keeping ON pressed, click the SYMB key (don't hold it down too long or you'll go into an update mode which requires a pin in the back to get out).

Or if you have a pin/paperclip, there is a little reset button in the back.
