    FAQ

    How many megabytes are in a gigabyte?

    This converter uses the binary gigabyte: 1 GB = 1,024 MB = 2¹⁰ MB, the scale reported by operating systems, RAM specifications and programming languages. Storage and mobile-plan vendors usually count decimally, 1 GB = 1,000 MB, and IEC 80000-13 names the binary units gibibyte (GiB) and mebibyte (MiB).

    What is the formula to convert gigabytes to megabytes?

    Multiply the number of gigabytes by 1,024: MB = GB × 1,024. For example, 1 GB = 1,024 MB, 0.5 GB = 512 MB and 8 GB = 8,192 MB. The reverse conversion divides megabytes by 1,024.

    How do you convert gigabytes to megabytes in your head?

    Add three zeros (multiply by 1,000) and then add 2.4% — that is exact, because 1,024 ÷ 1,000 = 1.024. For 8 GB it gives 8,000 + 192 = 8,192 MB, and for 16 GB it gives 16,000 + 384 = 16,384 MB.
