what units the programs involves are calling "mb/s".
Maybe one of them thinks it means megabytes and
another thinks it means megabits :-).

Generally people are starting follow the standards, although that's only 
generally:
 mb or mbit bits
 mB  bytes x 1000000
 miB bytes x 1024*1024
Since a common rate in the 802.11 standard if 54 mbit that's probably right.

My Intel 2200 wireless:
eth0      IEEE 802.11bg  ESSID:"TMR-2"
          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:02:6F:5D:79:48
          Bit Rate:54 Mb/s   Tx-Power=20 dBm   Sensitivity=8/0
          Retry limit:7   RTS thr:off   Fragment thr:off
          Encryption key:RedacteD   Security mode:open
          Power Management:off
          Link Quality=93/100  Signal level=-35 dBm  Noise level=-87 dBm
          Rx invalid nwid:0  Rx invalid crypt:1  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:5

And Ralink on USB with rt2800usb driver:
wlan0     IEEE 802.11bgn  ESSID:"TMR-2"
          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:02:6F:5D:79:48
          Bit Rate=81 Mb/s   Tx-Power=27 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on
          Link Quality=56/70  Signal level=-54 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:15   Missed beacon:0

802.11n uses 2.462Mb band and/or 5.xxx Mb band, the high band being less noisy in many cases and possibly giving a cleaner connection.
