 I'm quite sure Tor reports consensus bandwidth in kilobytes, not
 kibibytes:
 https://github.com/torproject/tor/blob/master/src/feature/dirauth/bwauth.c#L191,
 https://github.com/torproject/torspec/blob/master/dir-spec.txt#L2387

 > but the difference between 1000 and 1024 is not very important, because
 bandwidth measurements are only 20-59% accurate anyway.
