What options does wget --report-speed take?

When I do this command: wget --report-speed=type they only *type* it accepts is bits. It won't have numbers, kilobits / kilobytes or bytes. The help page (wget --help) says: --report-speed=TYPE Output bandwidth as TYPE. TYPE can be bits. suggesting that they TYPE **can** be something else? What options does it take that I haven't found, and (if this option doesn't do this) how can I force the speed to be displayed as bytes or Kilobytes.
