Actually it isn't the telco types at all. The more normal use of these things is that k/K and m/M are 1000 and 1000000 when you talking about anything other than storage capacities. When talking about storage is when you get the miss-usage of k/K and m/M meaning 1024 and 1048576. I have never seen anyone measure bandwidth using the base 2 miss-usage of the SI unit suffixes. -- Rod Grimes - KD7CAX @ CN85sl - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
