MB Converter

Converts megabytes to gigabytes, kilobytes and bytes using 1000 and 1024, and shows how much space the file will take in Windows.

A gigabyte holds 1000 megabytes under the decimal rule and 1024 under the binary one. Both answers are in the table beside, and you can type the unit right in the field: "4700 MB".

Why a file size doesn't match

A 700 MB file from a product description will show as 667 MB in Windows if the author counted by 1000. When the size uses 1024, the numbers agree.

Megabytes and megabits

A 100 Mbit/s plan means 12.5 MB per second: a byte has 8 bits. The download time calculator will estimate how long a file takes to download.
