It’s enough for some people just to plunk one value into a box and watch the conversion come out the other end, but we’re savvy here, right?
The newly released free version of Aperture Mobile’s Converta app thinks you are, and that’s why it actually bothers showing you what it’s doing. The free version calculates the equivalent values of angles, lengths, mass, temperatures, and volumes, and the $0.99 paid version includes things like illumination, radiation, velocity, and energy. You can also choose between a keypad and a clever gestural interface.
I’m not sure how useful the radiation conversion would be to most people, but it’s nice to know it’s there..
