Sweet! You just purchased a 32GB Edge flash drive to store your files, but now you're wondering what the heck this drive can actually hold — how many MP3s? Movies? This is all important information! Well Sensible Units will help you on your quest, taking any unit of size (not only tech related) and converts it into real-world objects. I suggest playing around with it. . . Who knew that 5cm was 6.3 dry basmati rice grains end to end? Or that 4 MBs is only equivalent to 1.3 MP3s worth of songs?! Love it!
