How could I possibly implement a unit converter in Java??? I was thinking of having a abstract base class: 

public abstract class Unit {
    ...
    public void convertTo(Unit unit);
}

Then having each class like Meter Kilometer Inch Centimeter Millimeter … derive from that base Unit class. All the units of length would be in a package called com.unitconverter.distance, then a package, com.unitconverter.energy, for energy etc. etc. So is this the best way to implement a unit converter? Or is there a better or more easier way?

    There’s been a fair amount of work on this, including JSR 108 (withdrawn) and JSR-275 (rejected). See JScience and UnitsOfMeasure implementations of the latter
