Similar to OpenAL, the units used in the coordinate system are not defined, and do not need to be.

Quoting from the OpenAL spec:

3.3. Space and Distance
OpenAL does not define the units of measurement for distances. The application is free to
use its own units, for example, meters, inches, or parsecs. OpenAL provides means for
simulating the natural attenuation of sound according to distance, and to exaggerate or
reduce this effect. However, the resulting effects do not depend on the distance unit used
by the application to express source and listener coordinates. OpenAL calculations are
scale invariant.
