【實用工具app】Convertor|最夯免費app-綠色工廠好玩App

A beautiful, innovative, efficient, and truly functional conversion application; and a great yet simple educational tool.

"Convertor" is intended to be the most efficient and elegant conversion application on the iPhone or iPod Touch. It allows one to very quickly convert a number to a new unit, explore new scales in Nature, teach about precision and scientific notation; and all this through a gorgeous interface that maximally leverages intuitive touch gestures for efficiency.

Quick and efficient

-------------------

As soon as you launch the app, a colorful panel is presented giving you immediate access to nine different conversion measures: length, area, volume, time, speed, mass, energy, force, and pressure. Just swipe to dial in an input number; double tap to increase/decrease orders of magnitudes quickly, and to increase/decrease precision if desired. Simply tap and swipe to convert your input to a desired unit or explore other units efficiently.

Educational

-----------

Employing scientific notation, the app also teaches one to focus on the significant figures of a number; great for high school students learning about the meaning of numbers in the sciences. Interesting units allow one to explore the natural scales of quantum mechanics, relativity, and gravity; while still providing common units in a range of field from Physics, Chemistry, and Astrophysics, to applied sciences, construction, and even cooking!

Features
