Whatever a unit is, that is totally dependent on scale and your renderer. The data in postgresql is vector data and has no scale. The coordinates of the reference system 900913 are metric, so you can calculate with them. The values of your bounding box are in meters, so you can calculate the current scale of your data with the corner values of the bounding box.
