Hi!
How many gigs are in one mbps?
Thanks!

a megabit line will transfer about 360 gigabyes monthly

I've seen companies say 300GB and I've seen companies say 320GB.

You can cout it up.

1 mb per sec is 60 mb per min, is (60x60) 360 mb per hour, is (24x360) 8640 mb per day, is (7x8640) 60480 per week and is (4 x 60480) 241920 per 4 weeks is over 240 gig, for a full month (30 days) is that 256 mb per month. But that is mathematics :D

Jacco

(30 days) is that 256 mb per month. But that is mathematics

Well, uh, lol, not really.

1Mb (megabit) continuous for 30days = a theoretical maximum of 324GB (gigabytes) of data transfered.

I'd love to see the math on that one..... I've seen a few companies offering 1mbps connection claiming it's 360gb, personally i think thats a total scam considering no matter what you do, the math wont work for that :D.

1,000,000 bits per second divided by...
8 bits per byte equals...
125,000 bytes per second.

125,000 bytes per second times...
60 seconds in a minute times...
60 minutes in an hour times...
24 hours in a day equals...
10,800,000,000 bytes per day.

Now here comes the variables:

Some people consider one gigabyte to be 1,073,741,824 bytes, while other people consider one gigabyte to be 1,000,000,000 bytes.

So for the sake of clarification:

- 1 GB (gigabyte) = 1,000,000,000 bytes
- 1 GiB (gibibyte) = 1,073,741,824 bytes

So depending on how many days you consider a month to be...

28 days = 302,400,000,000 bytes or 302.4 GB or ~281.631946563... GiB
29 days = 313,200,000,000 bytes or 313.2 GB or ~291.690230369... GiB
30 days = 324,000,000,000 bytes or 324 GB or ~301.748514175... GiB
30.5 days = 329,400,000,000 bytes or 329.4 GB or ~306.777656078... GiB
31 days = 334,800,000,000 bytes or 334.8 GB or ~311.806797981... GiB

So you see, the answer to that question depends on how many bytes you consider a gigabyte to be, and how many days you consider a month to be. Too many variables exist to give a definite answer. That should be enough math to make you sick. :puke:

We base it on 312.5GB

Most traffic is in the day / night, not the sleeping hours :). You won't max out then.

For the sake of all that, lets say 330GB~ MAX per month, if the line was used ALL the time.

Let's dance, we found a soultion :)

Not really. You could start getting into the 95th percentile, and it's a whole different story

324, each way.

1 Mbps-day = 10^6 b/s * 60 s/m * 60 m/h * 24 h/day * 1 day = 8.64 * 10^10 bits = 1.08 *10^10 bytes = 10.8 GB.

1 Mbps-month is between 28 * 10.8 GB = 302.4 GB and 31 * 10.8 GBN = 334.8 GB. An average month has 146097/4800 = 30.436875 days, so an average Mbps-month is 328.71825 GB.

Now, for traffic levels above 5 Mbps, the 95th percentile level will *typically* be between 1.45 and 1.55 times the average level. Consequently, 1 95th-percentile-Mbps-month is about 210-230GB. Note that this will vary depending upon the "burstiness" of your traffic (if you get all your traffic between 6PM and midnight, you'll get far fewer GB per Mbps).

Most networks see peak levels which are 50% higher than 95th percentile levels, with very large aggregates (eg, multi-Gbps links) only around 30% above their 95th percentile. Consequently, if you want to avoid significant performance loss, you should expect to get no more than 140 - 150 GB per "capped" Mbps.

You realize thats WAY to much math for 1:30am? :D

You realize that
1. I have a first class honours degree in mathematics,
2. I'm now studying at Oxford University, and
3. It's 7:30 AM here? :D

I could have guessed the first two :D But had no clue what timezone your in.. Answers a lot of questions about some of your late night posts :D

I'd completly agree with you, its 324GB..

I missed the 30.4xxx average days in a month, so its a toss up, do you assume the .4xxxx or just say "every month has 30 days"..... ahh well, for 30 days, its 324, thats a tad simpler even if it is 4gb off :).

Well then you also need to figure in for leap years.. And the months where you have Daylight savings time, if your area observes daylight savings time :D Hey an extra out can make a differnce :D

Daylight savings times dont come into play now do they? They even out within a 1 year span, hence it's a null :)

It evens out in a year.. But not in a month :D

It can add or subtract an extra hour to a single month's transfer depending on your locaction and their observance of it :D

Well yeah, but leapyears are over a period of years, not a month, calculations like that are based on 1+ years usually when figuring out the days to a year :)

But you know how customers can split hairs sometimes..

Hell you delt with me an Jen enough :D

Either way, if you build a business model on 1Mbps = 324GB per month, you're gonna get a nasty surprise when you start to reconcile your upstream's 95th based bill with your GB-based receivables.

On average i find we get 250gb to 1mbps, but 1mbps == 324gb, billing methods will not change this, they will simply vary your milage.. If you fail to take into account your billing method, you've got far bigger issues to take care of, eg. your severe lack of throughness.

Hey Myles,

I understand your point, and I agree with what you're saying in principle. But 1mbps == 324GB only as a mathematical exercise, and I think it's misleading to suggest real-world results are anywhere close to that. After all, a 'billing method' is inherent to every single deal that's ever been brokered in this industry, right? ;)

Without getting into a debate over the specifics of different billing methods, most folks here usually want to determine how much traffic they can expect to receive (in GB) for a given 1mbps commitment - usually on 95th percentile. That's what started this thread, if I recall correctly. Anyway, our clients who bill out at 1mbps on 95th range anywhere from 175GB on the low end to around 250GB on the high end. My only point is this - if you're planning to build a business model based on $/GB receivables - and you're upstream is charging you based on 95th percentile billing - then using 1mbps = 324GB could lead to unexpected results. As you indicated, it's imperative to thoroughly understand your billing method. :)

I think you and I obviously agree here, I'm just trying to spell it out a little more clearly for the young 'uns.

Brandon

Yep,

Just make sure you indicate somewhere that "your milage may vary" :). We actually usually get over 250GB to 1mbps, but thats counting in and out average (but i mean hey, thats how GB's are measured right?)..... I'd hate to advertise that and have someone only get 50GB to 1mbps.... man, i'd have something nipping in my bottom pretty darn fast in that case :eek:
