Physical Units Package

I have written a Java class package for dealing with physical units in programs. For those of you who don't realize what I'm talking about. I needed a way to represent the units that a value may have in a typical science or engineering program. For instance, something may have a value of 35.67 with the units of "meters". This package allows you to identify and convert between the units that are associated with some value in your program. My design requirements for this class are as follows:

• Must be able to represent any unit that a parameter may have in an object.
• When given a value in one set of units, the object must be able to convert that value to another set of compatible units.
• A method must exist for returning the conversion factor between any set of compatible units (like the factor for converting between meters and feet).
• Attempts to convert between incompatible unit types must be caught at compile time whenever possible and an exception should be thrown at run time if nothing else.
• It must be easy to add new unit types to the list of units that can be worked with by the package.

If you download my units package and use it. Let me know what you think.
