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.
A petabyte (PB) is equal to 1,024 terabytes (TB), so 1,024 petabytes is equivalent to 1 exabyte (EB). In terms of bytes, 1 petabyte is approximately 1,024^5 bytes, which equals about 1,125,899,906,842,624 bytes. Therefore, 1,024 petabytes equals approximately 1,125,899,906,842,624,000,000 bytes, or 1.125 exabytes.
PB = PetaByte = 2 to the 50th = 1,125,899,906,842,624 bytes
A petabyte is a unit of digital information storage equal to 1,024 terabytes, or approximately 1 quadrillion bytes (1,000,000,000,000,000 bytes). In terms of data, a petabyte can store about 500 billion pages of standard text or roughly 200,000 high-definition movies. It is commonly used to measure large data sets in fields such as big data analytics and cloud storage.
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
