Sick of the regular old Windows calculator? Need some spice in your life? Want some excitement with your equations? You need Microsoft Calculator Plus!
It isn’t new, but I just noticed it. Not a bad product. Calculator Plus is just regular calculator with an extra option to do conversions (measurements, currency) and an optional slicker UI. The slicker graphics seem easier to use if you tend to need to do quick calculations with just the mouse, so it might be worth it. Just for conversions, though, its a worthy download. And, of course, its free.
