Network bandwidth is traditionally measured in bits/second, either Kbps, Mbps or Gbps.

Additionally, the current real time server stats display network utilization as KByte/sec, even when this is in the hundreds of thousands of Kbyte/sec.

mongostat supports scaled units, however that may be disabled to aid in parsing the output.

Finally, the display indicates "KB", however it should be "KB/s" for the current configuration. Of course, when scaled (changing) units are available in bits, then it should change accordingly: Kb/s, Mb/s and Gb/s.
