Understanding file size (Bytes,KB MB GB TB PB EB ZB YB)

A byte is a sequence of 8 bits (enough to represent one alphanumeric character) processed as a single unit of information. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits).

1 KB Kilobyte = 1,024 Bytes

1 MB Megabyte = 1,048,576 Bytes

1 GB Gigabyte = 1,073,741,824 Bytes | One billion Bytes

1 TB Terrabyte = 1024 GB, = 1,048,576 MB,= 8,388,608 KB,= 1,099,511,627,776 Bytes and 8,796,093,022,208 bits.

1 PB Pettabyte = 1024 TB, = 1,048,576 GB, = 1,073,741,824 MB, = 1,099,511,627,776 KB,= 1,125,899,906,842,624 Bytes and 9,007,199,254,740,992 bits.
