PC File Size Conversion Table

Giga, mega, tera, kilo? What do they mean? Do you need to find out how many megabytes are in a petabyte, or home many decimal places a gigabyte holds? Do you know there is such a word as yottabyte ? The table below shows the simple relationship between the file storage sizes that computers use.

Binary calculations are based on units of 1,024, and decimal calculations are based on units of 1,000. It should be noted that decimal calculations are based on units that have been rounded off to the nearest 1,000 and therefore differ from the actual number of bytes used in binary calculations. If you don’t understand, just observe the conversion.

kilobyte (KB) = 1024 bytes
megabyte (MB) = 1024 KB
gigabyte (GB) = 1024 MB
terabyte (TB) = 1024 GB
petabyte (PB) = 1024 TB
exabyte (EB) = 1024 PB
zettabyte (ZB) = 1024 EB
yottabyte (YB) = 1024 ZB
