How many KB/s = 100MB per hour?
« on: September 25, 2008, 06:43:38 PM »

A question for some of the more knowledgeable folk here on the forum.
(More knowledgeable than me that is)

During my "Traffic Management period" I am allowed to DL 1,000 MB in a 5 hour period!

How many KB/s (not Kb/s) would it take to DL say 200MB/hour?
or, as below.

25KB/s = ?? MB/hr
30KB/s = ?? MB/hr
35KB/s = ?? MB/hr
40KB/s = ?? MB/hr
45KB/s = ?? MB/hr

50KB/s = ?? MB/hr
60KB/s = ?? MB/hr
70KB/s = ?? MB/hr
80KB/s = ?? MB/hr
90KB/s = ?? MB/hr
100KB/s = ?? MB/hr

At the moment I seem to have a answer for "50KB/s = 200MB/hr (approx)"

Obviously some of the above can just be doubled up etc to give the answer, but I need a guideline to start with please.

There's a little area of doubt over the definition of a megabyte, but taking a megabyte to mean 1000 kilobytes, then

1 KB/s = 3.6 MB/hr

so the approx figure for 50 KB/s would be 180 MB/hr, not 200.

Ok, thanks, thats' what seems to work out on he figures I have been saving from Netlimiter.

As you say 1000 and 1024 can both equal 1MB but my program uTorrent does not go into fine detail (unless it's in the "Help" menu) and I hate help menu's.
But the good news is that seems to be what I wanted.

The bad news is "I have just gone over my limit by 10MB) so may now have to suffer a 5 hour penalty of being reduced to a 1MB rate. (When they eventually decide to implement it)
Thanks.

I just decided to do a speed test to see if the cap had started.
But it seems that my upgrade has "finally" been done.

Not that VM bothered to tell me.

I can't seem to think what the result would be if the figure we were talking 1024kb = 1MB
and not 1000kb.

If a megabyte is 1024 kilobytes then

1 KB/s = 3.516 MB/hr

and 50 KB/s = 175.8 MB/hr

Most ISPs tend to use 1000 rather than 1024.

I believe it started because BTw use the decimal figure on their RADIUS profiling system information that can then be passed on to the IPStream ISPs.
However some ISPs do their own measuring - since Virgin cable doesnt use adsl I'm not sure which system they use.

The decimal and binary debate has raged for many years..  Im led to believe that capacity is measured in decimal whilst speed is measured in binary.
Capacity includes things like storage devices (HDDs) and the amount of useage you have consumed (downloaded), although personally Im still not convinced and no doubt it will continue to be a topic of debate for many years to come.

Dont forget that some ISPs only measure downloaded.. whilst with others its download and upload.   If youre downloading then you will also consume a small amount of uploads.

Thanks both.

What I was doing was setting the parameters in uTorrents Scheduler "Time and UL & DL rate"
Which are labelled as KB/s, so that I could have the optimum setting ensuring I did not go over my UL/DL limit at certain times of the day/evening, thus being able to "set-it and forget-it" (VM's Traffic Management "v" oldfogy's traffic management)
(Scheduler in uTorrent enables UL/DL to be either stopped, started or to reduce the BW at specified times.)

So with taking a reading from Net-Limiter, again labelled in KB, I could then work out from how many MB I had uploaded/downloaded, but needed to then convert this back to KB/h.

Result =
A 65KB/s DL setting for the evening duration of 5 hours would ensure I did not go over 1,200MB DL during that period.
And a 38KB/s setting for the UL would also also ensure I did not go over 700MB DL during the same period.

No allowances have been made for a slower UL/DL connection so figures are "safe Maximums"

I know there is also a morning "allowance" but thats different and wont go into that, except the setting works out at DL rate = 138KB/s

Maybe I have gone around this a long way, I don't know, but it now works and was the only way I could think of doing it without having to monitor it over a long period.
Hope that makes sense.

At a "quick" glance I don't think it would have answered my question (which has now been sorted) but thanks all the same.
