alter standard:
bit b 0 or 1
byte B 8 bits
kilobit kb 1000 bits
Kilobyte (binary) KB 1024 bytes
Kilobyte (decimal) KB 1000 bytes
Megabit Mb 1000 kilobits
Megabyte (binary) MB 1024 Kilobytes
Megabyte (decimal) MB 1000 Kilobytes
Gigabit Gb 1000 Megabits
Gigabyte (binary) GB 1024 Megabytes
Gigabyte (decimal) GB 1000 Megabytes
Terabit Tb 1000 Gigabits
Terabyte (binary) TB 1024 Gigabytes
Terabyte (decimal) TB 1000 Gigabytes
Petabit Pb 1000 Terabits
Petabyte (binary) PB 1024 Terabytes
Petabyte (decimal) PB 1000 Terabytes
Exabit Eb 1000 Petabits
Exabyte (binary) EB 1024 Petabytes
Exabyte (decimal) EB 1000 Petabytes

binär:
1 bit (b)
1 byte (B) = 8 bits
1 Kilobyte (K / KB) = 2^10 bytes = 1,024 bytes
1 Megabyte (M / MB) = 2^20 bytes = 1,048,576 bytes
1 Gigabyte (G / GB) = 2^30 bytes = 1,073,741,824 bytes
1 Terabyte (T / TB) = 2^40 bytes = 1,099,511,627,776 bytes
1 Petabyte (P / PB) = 2^50 bytes = 1,125,899,906,842,624 bytes
1 Exabyte (E / EB) = 2^60 bytes = 1,152,921,504,606.846,976 bytes
1 Zettabyte (Z / ZB) = 2^70 bytes = 1,180,591,620,717,411,303,424 bytes
1 Yottabyte (Y / YB) = 2^80 bytes = 1,208,925,819,614,629,174,706,176 bytes

Note: In the metric system the "k" or "kilo" prefix is always lowercase but since these binary uses are not properly metric, it has become standard to use an uppercase "K" for the binary form.

dezimal:
1 bit (b)
1 byte (B) = 8 bits
1 Kilobyte (K / KB) = 10^3 bytes = 1,000 bytes
1 Megabyte (M / MB) = 10^6 bytes = 1,000,000 bytes
1 Gigabyte (G / GB) = 10^9 bytes = 1,000,000,000 bytes
1 Terabyte (T / TB) = 10^12 bytes = 1,000,000,000,000 bytes
1 Petabyte (P / PB) = 10^15 bytes = 1,000,000,000,000,000 bytes
1 Exabyte (E / EB) = 10^18 bytes = 1,000,000,000,000,000,000 bytes
1 Zettabyte (Z / ZB) = 10^21 bytes = 1,000,000,000,000,000,000,000 bytes
1 Yottabyte (Y / YB) = 10^24 bytes = 1,000,000,000,000,000,000,000,000 bytes

Note: A third definition of Megabyte is that used in formatting floppy disks: 1 Megabyte = 1,024,000 bytes.

bsp.:
64 kbit/s = 8 kB/s
1 Mbit/s = 128 KB/s
768 kbit/s = 96 kB/s


neuer standard:
bit bit 0 or 1
byte B 8 bits
kibibit Kibit 1024 bits
kilobit kbit 1000 bits
kibibyte (binary) KiB 1024 bytes
kilobyte (decimal) kB 1000 bytes
megabit Mbit 1000 kilobits
mebibyte (binary) MiB 1024 kibibytes
megabyte (decimal) MB 1000 kilobytes
gigabit Gbit 1000 megabits
gibibyte (binary) GiB 1024 mebibytes
gigabyte (decimal) GB 1000 megabytes
terabit Tbit 1000 gigabits
tebibyte (binary) TiB 1024 gibibytes
terabyte (decimal) TB 1000 gigabytes
petabit Pbit 1000 terabits
pebibyte (binary) PiB 1024 tebibytes
petabyte (decimal) PB 1000 terabytes
exabit Ebit 1000 petabits
exbibyte (binary) EiB 1024 pebibytes
exabyte (decimal) EB 1000 petabytes

binär:
1 bit (bit)
1 byte (B) = 8 bits
1 kibibyte (KiB) = 2^10 bytes = 1,024 bytes
1 mebibyte (MiB) = 2^20 bytes = 1,048,576 bytes
1 gibibyte (GiB) = 2^30 bytes = 1,073,741,824 bytes
1 tebibyte (TiB) = 2^40 bytes = 1,099,511,627,776 bytes
1 pebibyte (PiB) = 2^50 bytes = 1,125,899,906,842,624 bytes
1 exbibyte (EiB) = 2^60 bytes = 1,152,921,504,606.846,976 bytes
1 zebibyte (ZiB) = 2^70 bytes = 1,180,591,620,717,411,303,424 bytes
1 yobibyte (YiB) = 2^80 bytes = 1,208,925,819,614,629,174,706,176 bytes

Note: For consistency with the other prefixes for binary multiples, the initial "K" used in the abbreviation for kibibyte (2^10) has been capitalised.

dezimal:
1 bit (bit)
1 byte (B) = 8 bits
1 kilobyte (kB) = 10^3 bytes = 1,000 bytes
1 megabyte (MB) = 10^6 bytes = 1,000,000 bytes
1 gigabyte (GB) = 10^9 bytes = 1,000,000,000 bytes
1 terabyte (TB) = 10^12 bytes = 1,000,000,000,000 bytes
1 petabyte (PB) = 10^15 bytes = 1,000,000,000,000,000 bytes
1 exabyte (EB) = 10^18 bytes = 1,000,000,000,000,000,000 bytes
1 zettabyte (ZB) = 10^21 bytes = 1,000,,000,000,000,000,000,000 bytes
1 yottabyte (YB) = 10^24 bytes = 1,000,000,000,000,000,000,000,000 bytes

Note: Note the use of a lowercase "k" in the abbreviation for kilobyte, in keeping with the metric system.
