Google is wrong in this case.  Network rate measurements have always
been the base 10 units.  (Disks on the other hand have historically
used the base 2 units in the past but have changed to the base 10
units in the not terribly distant past.)

Both Iperf 2 and Iperf 3 use the base 10 units (1000*1000) when
talking about the transfer rate.  When talking about the volume of
data transferred they use the base 2 units (1024*1024).

Hope that helps,
