95546202k = ?

I'm sorry but I'm tired and I need a little math help if someone would be so kind.

Let's say I transfer 95,500,000k in a given month. What is the total transfer in terms of GB? I calculate it at 95GB but that doesn't seem right considering this website has over a million registered users and just as many page views per month (1.7 million).

Is my bandwidth calcs correct?

91Gb seems about right. That gives an average page size of 56k, which seems alright; I'm guessing this is a forum.

Perhaps there's bit/btye confusion and it's really 91*8, though.

One of the most confusing things in the hosting business when you first start is the terms Mbps, GB, and MB. They are not equal!!! Here is how you break it down:

1 Mbps = 1 Megabit per second = 1024 Kilobits per second

1 MB = 1 Megabyte = 1024 Kilobytes

Using that:

1Mbps = 128 Kilobytes per second

so now we can see that:

1Gigabit = 1024 Megabits

61,440 Kilobits a minute = 60 Megabits a minute = 7.5 Megabytes a minute

Also with those previous calculations you can get:

450 Megabytes in an hour

10,800 Megabytes in a day = 10.54 Gigabytes

334,800 Megabytes a month = 326.95 Gigabytes a month

If this is wrong someone please correct me.

If you want to get really pendantic then there's Kibibits, Mibitis and so on, but I fall asleep at that point.

MrManager, you're right, that's about 95GB (assuming your k stands for kiloBYTES.. if it's kiloBITS, that's about 11.3 gigabytes.
Atomic Haven, you're wrong, mega- is 1000 kilo-, giga- is 1000 mega-
On a 100mbit connection, you could theoretically push in or out 12.5 megaBYTES a second.

Sorry. 1000 is a raw estimate. It is really 1024 for both figures.

You can push more than 7.5MB/second Atomic. I do it all the time over local LAN servers via http downloads. I got a tad over 12MB/second before .

I guess you mean raw throughput, in which case I've not hit it but I wouldn't disagree that it's possible on a LAN.

I stand corrected, thanks guys! I thought the numbers looked a bit fishy...

Here is the correct calculation

1 MB = 1024 KB
1 KB = 1024 Byte
1 Byte = 8 Bits

if you have a 100 Mbit/s Card;

100 Mbits = 100 Mbits / 8 Bits = 12,5 MBytes

( You can test with 2 computers one has ftp server and one has ftp client software with directly connected via 100 mbit ethernet cards .. Send a big file like a divx film look at speed you can see 12,5 Mb but not always.. )

You can push 12,5MB per second..
12,5 MB x 60 (secs) = 750 MByte a minute
750 MB x 60 ( mins ) = 45000 MByte a hour
43,9453125 GB x 24 (hour) = 1054,6875 GB a Day
1054,6875 GB x 30,5 ( days ) = 32167,96875 GB a Month
31,414031982421875 TB
31,414031982421875x8 = 251,312255859375 Tbits

but non of the ethernet cards can always go with 12,5 MBps
it will go ave. 6,5 - 8 MBps... Sometimes 5 sometimes 10

if you take it from 7 MBps
7x60x60x24x30,5 = 18446400 MBps = 18014,0625 GBps = 17,59185791015625 TBps
= 140,73486328125 Tbits
nearly 141 Tbits
you can see if your home connection not unmetered like 256Kb dsl.. your max. download speed 32KB but you can see 25-28 KB max. cause of packet headers

if you have 1200 gbits for a month..
1200 / 8 = 150 GB a month = 153600 MB
153600/30,5 = 5120 MB for a Day
5120 / 24 = 213,33 MB for a hour
213,33 / 60 = 3,55 MB = 3635,2 KB for a Minute

60,58 KB for a second
You must go with this speed

if you have 1200 GBytes for a month...
1200 / 30,5 = 39,34 GB = 40284,16 MB for a Day
40284,16 / 24 = 1678,5 MB for an hour
1678,5 / 60 = 27,975 MB for a minute
27,975 * 1024 = 28646,4 KB
28646,4 / 60 = 477,44 KB for a Second...

you can now see
60,58 * 8 = 484,64 Kbits nearly 0,5 Mbits
477,44 * 8 = 3819,52 Kbits nearly 3,8 Mbits
they are not equal

95546202k = ?

here we go..
if it is kbits
it is 11943275,25 KBytes
it is 11663,35 MBytes
it is 11,390 GBytes = 11,4 GBytes

if it is Kbytes
it is 93306,83 MBytes
it is 91,12 GBytes

LOL Thanks- that took a while to read through but helpful nonetheless. Thanks! I'm just not used to seeing 1,000,000+ page views per month using so little bandwidth.
