This converter turns mebibytes into gigabytes instantly, using the exact factor 1 mebibyte = 0.001048576 gigabytes. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
1,024 kibibytes; why a "1 TB" drive shows as 931 GiB. One billion bytes — how storage and mobile data are sold.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
mebibytes- The amount you are converting, measured in mebibytes
0.001048576- The exact number of gigabytes in one mebibyte
gigabytes- The converted result
How it works, step by step
- Enter the number of mebibytes you want to convert.
- The value is multiplied by 0.001048576, the exact conversion factor.
- The result is displayed in gigabytes, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 mebibytes
Multiply 5 by 0.001048576. That gives 0.005243 gigabytes. A quick sanity check: one mebibyte is smaller than one gigabyte, so the number should get smaller — and it does.
Converting 72 mebibytes
72 × 0.001048576 = 0.075497 gigabytes. Working backwards, 0.075497 ÷ 0.001048576 returns 72 mebibytes, which confirms the factor is applied the right way round.
