Isn't that a little misleading? It calculates the potential total transfer on a per-Mbps basis, assuming that you maxed out the line continuously - which would give you horrible performance 24 hours/day. Not to mention, most usage patterns rise and fall, so you're either not getting full utilization some of the time, or you're badly oversubscribing some of the time.

Saying that 5Mbps is equivalent to 1674 GB/month isn't true if you are talking about Web browsing. It's true if you had two systems transferring data for some other reason (ie, non-human non-interactive usage such as backups).

The program is for converting what something like MRTG says is your average usage. If MRTG reports you using an average of 1MBPS then you are probably doing some kind of a bell curve that goes above 1MBPS and below it, but averaged out is equal to 1MBPS.

Does that make sense? So the program is just to help you figure out how many GB on average per month (or in X number of days) you use instead of KBPS or MBPS.

As an example (in 5 min intervals):

Reading 1 -> 128 kbps
Reading 2 -> 50 kbps
Reading 3 -> 512 kbps
Reading 4 -> 180 kbps

So the average of these 4 readings is 217.5 kbps if this stays the same for a 31 day period then you will have used 72.819 GB of bandwidth. ((kbps / 1000) *10.8) * 31 days

All the program does is that formula for you automatically.

Absolutely that makes sense and is a good usage. If it doesn't state that on the program's Web page, you should add it :)

I've certainly seen hosts who equate a 1Mbps bandwidth limiter with 10.5GB/day or whatever that works out to, though, which is why I made the comment.

Actually it doesn't state that on the page....and you're right...I should add it...hehe...thanks :)

a very handy tool

heres another one :)
