units

b = bit
B = Byte
Kib = kibibit
kb = kilobit
KiB = kibibyte
kB = kilobyte
Mb = megabit
MiB = mebibyte
MB = megabyte
Gb = gigabit
GiB = gibibyte
GB = gigabyte
Tb = terabit
TiB = tebibyte
TB= terabyte
Pb = petabit
PiB = pebibyte
PB = petabyte
Eb = exabit
EiB = exbibyte
EB = exabyte


Connection Speeds

bs = bit/s
Bs = Byte/s
Kibs = kibibit/s
kbs = kilobit/s
KiBs = kibibyte/s
kBs = kilobyte/s
Mbs = megabit/s
MiBs = mebibyte/s
MBs = megabyte/s
Gbs = gigabit/s
GiBs = gibibyte/s
GBs = gigabyte/s
Tbs = terabit/s
TiBs = tebibyte/s
TBs = terabyte/s
Pbs = petabit/s
PiBs = pebibyte/s
PBs = petabyte/s
Ebs = exabit/s
EiBs = exbibyte/s
EBs = exabyte/s


Usually ips write what speed you get in kbs (kilobits/s).



And now i will try to explain how you can convert kbs to KBs etc:

1000 bit = 1 kilobit
1000 kilobit = 1 megabit
1000 megabit = 1 gigabit
1000 gigabit = 1 terabit
1000 terabit = 1 petabit
1000 petabit = 1 exabit

1024 bits = 1 kibibit
1024 byte = 1 kibibyte
1024 kibibyte = 1 mebibyte
1024 mebibyte = 1 gibibyte
1024 gibibyte = 1 tebibyte
1024 tebibyte = 1 pebibyte
1024 pebibyte = 1 exbibyte

8 bit = 1 byte
1024 byte = 1 kilobyte
1024 kilobyte = 1 megabyte
1024 megabyte = 1 gigabyte
1024 gigabyte = 1 terabyte
1024 terabyte = 1 petabyte
1024 petabyte = 1 exabyte

Well this doesnt help us much, cuz we need to figure out how many 1 megabit is in kilobyte

1 kilobit = 1000 bit = 125 byte
1 megabit = 1000 kilobit = 125 kilobyte
1 gigabit = 1000 megabit = 125000 kilobyte
1 terabit = 1000 gigabit = 125000000 kilobyte
1 petabit = 1000 terabit = 125000000000 kilobyte


I hope this explains abit, and if not, im just gonna try to give a few examples. on some known connection types, that ppl usually have with fiber or adsl.

256kilobit/s(256kbs) = 32kilobyte/s or 32kB/s or
512kilobit/s(512kbs) = 64kilobyte or 64kB/s or
768kilobit/s(768kbs) = 96kilobyte or 96kB/s or
1mbit/s(1mbs/1mbits) = 125kilobyte or 125kB/s or
10mbit/s(10mbs/10mbits) = 1250kilobyte or 1250kB/s or

and just for thoose who doesnt know, "/s" means "per second" so 256kbs = 256 kilobit per second

Usually ips write what speed you get in kbs (kilobits/s).

And they also advertise plans of 3Mbps as "3 MEGS" :eek13:

HDD manufacturers also take advantage of the MB/MiB confusion.

1024 byte = 1 kibibyte
1024 kibibyte = 1 mebibyte
...
1024 byte = 1 kilobyte
1024 kilobyte = 1 megabyte
Therefore, kibibyte = kilobyte and mebibyte = megabyte? :confused:

I can't figure the difference between kilo and kibi and mega and mebi.

If I got it correctly (probably not, lol):
kilo = 1024 bytes
kibi = 1000 bytes

mega = 1024 kilobytes
mibi = 1024 kibibytes

Although Wikipedia says 1KB = 1000 bytes and 1KiB = 1024 bytes, but also that it varies... it's really very confusing at times.

I think its 1024 KB = 1 MB

these proposed rules are really clumsy, caused by the need (what need :rolleyes:) to adjust everything to the SI system no matter if subsequent usage becomes unnatural - thats why there should have been made exceptions, since imo this system doesn't cut it

binary is more natural for computing and it should be left that way, ie. kilo=1024 for all binary sytems (like the computer system) and if there is need for calculating with 1000 it would be easier for example to just use the same suffix as before and just add a 'd' for decimal, like this:

1 kB=1024 B
1 kBd=1000 B

kB=kilobyte
B=byte
kBd=decimal kilobyte (meaning it is calculated with a decimal base) or

kB10

that way all the names stay the same, one just adds a symbol for decimal base, instead we have a plethora of different names for every unit prefix :rolleyes:

why make it simple when it can be complicated, eh?

edit:
oh yeah, did i mention they sound ridiculous?

mega=cool
mebi=lol

It doesn't matter which unit is chosen:
kilo, mega, giga, tera, peta, exa and so on: means base 1000:
kilo = 1 000
mega = 1 000 000
giga = 1 000 000 000
tera = 1 000 000 000 000
peta = 1 000 000 000 000 000

kibi where bi stands for binary means 1024=2^10.
so:
kibi = 1 024
mebi = 1 048 576
gibi = 1 073 741 824
tebi = 1 099 511 627 776
pebi = 1 125 899 906 842 624
