    1. Take the value in megabytes.
    2. Divide it by 1000 (the number of megabytes in one gigabyte).

    Example: 500 MB ÷ 1000 = 0.5 GB.

    Reverse formula (gigabytes to megabytes): MB = GB × 1000. Example: 0.7 GB × 1000 = 700 MB.

    The factor is a whole number (1000), so this one is easy to do in your head or with long division.

    About megabytes and gigabytes

    Megabytes (MB). A megabyte (MB) is 1,000,000 bytes in the decimal SI system used by storage makers. The binary mebibyte (MiB) is 1,048,576 bytes.

    Gigabytes (GB). A gigabyte (GB) is 1,000,000,000 bytes (decimal). Windows reports sizes in binary gibibytes (GiB, 1,073,741,824 bytes) but labels them GB.

    Frequently asked questions

    How many gigabytes in 1 megabyte?

    One megabyte equals 0.001 gigabytes. Looking at it the other way, one gigabyte is 1,000 megabytes.

    How do you convert megabytes to gigabytes?

    Divide the number of megabytes by 1000. For example, 500 MB ÷ 1000 = 0.5 GB.

    What is 700 megabytes in gigabytes?

    700 MB is 0.7 GB (cD capacity).

    How do I convert gigabytes back to megabytes?

    Multiply by 1000, or press the ⇄ swap button above. For example, 0.7 GB × 1000 = 700 MB.

    Why does my computer show a smaller size?

    Storage makers use decimal units (1 GB = 1,000,000,000 bytes) but Windows uses binary units (1 GiB = 1,073,741,824 bytes) while still writing GB. So a 1 TB drive shows as about 931 GB.

    Is this converter free and private?

    Yes. It is free with no sign-up, and every calculation runs in your browser, so nothing you type is sent to a server.
