Bytes Converter

Converts bytes to kilobytes, megabytes and gigabytes at once using both 1000 and 1024, and shows what Windows will display.

Type a number, and add the unit right in the field: "1.5 GB" or "512 KB". The result shows both conventions at once, base 1000 and base 1024, and whole bytes are printed in full.

1000 or 1024

Disk and flash drive makers count in base 1000: a gigabyte is a billion bytes. Windows and school computer science divide by 1024, so a 64 GB flash drive shows up as 59.6 GB in Windows. Under the IEC standard, the base-1024 units are called kibibytes (KiB), mebibytes (MiB), and gibibytes (GiB).

Bits and bytes

A byte holds 8 bits. Internet speeds are written in bits per second, while file sizes are in bytes. To estimate how long a file will take to download, use the download time calculator.
