Ten Apps That Add Functionality to Kindle Fire HD
If you need help converting just about anything to anything else (feet to meters, pounds to kilos, or whatever), you’ll appreciate this handy little app. It handles 2,400 different conversions, including height, weight, volume, volume to weight, and time to distance. Tap the Unit key, and you’ll see a list of the various types of conversions available.
Just fill in the You Have field and the You Want field, and then enter the number of units. Tap the equal sign (=) and get your conversion. Holding Kindle Fire HD in landscape orientation displays a few more helpful tools on the calculator-style interface.
