units for position & velocity

BrickFarmer
I managed to rebuild JOAL to work under OSX 10.8.5, and it seems to be working fine for me :) but I'm wondering what units the following calls are using.

        al.alSourcefv(source[0], AL.AL_POSITION, sourcePos, 0);
        al.alSourcefv(source[0], AL.AL_POSITION, sourceVel, 0);

meters and meters/second? or none at all?

Section 3.3 of the spec covers it thanks.  I would have cut and paste the relevant info here, but the formatting is crazy.  Anyway basically there are no units, so I'll just see what works :) Thanks.
