For the record, a more accurate formula to calculate utilization of an Ethernet link is this:
(160*(number of frames per sec)+8*(number of octets per sec))/10,000,000 The result is a number between 0 and 1; multiply by 100 if you need percentage. The 160*(number of frames per sec) part is necessary to account for the 64 bit preamble and the 9.6 usec inter-frame gap. Even this formula is an idealized one, as it doesn't account for collisions.
