This Clojure library defines data types that represent dimensions (length, time, mass, ...), units (m, km, ft, ...), and physical quantities (2 meters, 3 hours, ...). It allows the definition of any number of unit systems, even though for most applications the SI unit system (provided with the library) should be sufficient.

This library uses the still experimental deftype construct in the current development branch of Clojure. For this reason, this library cannot be considered ready for production code yet.

There isn't much documentation yet. Check out the docstrings and the scripts under "examples".
