1MB = 8,388,608 Bits 1MB = 1,048,576 Bytes 1MB = 1024 Kilobytes
1 petabyte (PB) = 1,000,000,000,000,000 bytes = 1015 bytes. 1 megabyte (MB) = 1,000,000 bytes = 106 bytes. So 1 petabyte = 1,000,000,000 megabytes. A related unit, the pebibyte (PiB) is 1024 terabytes, but this is rarely used, if ever.

Computer memory is divided into various sizes. A kilobyte (KB) is approximately 1000 bytes (the exact number is 1024)
20 terabytes is 20,480 gigabytes.
I don't know how to measure computer storage space in any units other than those you've already used. I guess I could give the value in bytes. A petabyte is 250 bytes, or (roughly) 1015 bytes.
PB = PetaByte = 2 to the 50th = 1,125,899,906,842,624 bytes
In actual size there are 1024 byte in a kilobyte. and 1024 kb in a megabyte. So 1024 bytes times 1024 kb would equal the number of bytes in a megabyte 1,048,576 bytes. Then multiply that by the number of megabytes being 700 in this case to get 734,003,200 bytes in 700 megabytes. Dznytoy

* 1 byte = 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 taken from beesky.com
1 PB = 1,000,000,000,000,000 B = 10005 B = 1015 bytes. 1,000,000 gigabytes http://en.wikipedia.org/wiki/Petabyte
Bytes of memory are chucks of code that help put a program or file together. The largest we have so far is petabyte then going down in size are: terabyte, gigabyte, megabyte, kilobyte, then just byte, then even smaller is a bit.
this is in order from samllest to biggest : Bit = 1bit Byte = 8bits Kilobyte (kB) = 1024 bytes or 10^3 Megabyte (MB) = 1048576 bytes or 10^6 Gigabyte (GB) = 1073741824 bytes or 10^9 Terabyte (TB) = 1099511627776 bytes or 10^12 Petabyte (PB) = 10^15 bytes Exabyte (EB) = 10^18 bytes Zettabyte (ZB) = 10^21 bytes yottabyte (YB) = 10^24 bytes (this is as far as i know)
