Units

Mathematica allows you to do arithmetic not only with symbols and numbers, but also with units. Mathematica's integration with Wolfram|Alpha allows for a sophisticated unit system that combines the flexibility of free-form linguistics with the computational power of numerical and symbolic algorithms. The units framework integrates seamlessly with visualization, numeric, and symbolic functions.
