Computer File Size Conversion Table


Computer File Size Conversion Table


The Computer File Size Conversion Table below shows the 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.
