How it works
Enter a value, select Gigabyte and Megabyte, then MimiFile calculates the result instantly using the conversion model for this category.
Convert gigabytes (GB) to megabytes (MB) using decimal SI storage prefixes.
Enter a value, select Gigabyte and Megabyte, then MimiFile calculates the result instantly using the conversion model for this category.
Multiply GB by exactly 1000 to get MB. This page uses decimal GB and MB; binary GiB and MiB are separate units.
Digital storage uses a base-unit scale model.
MB = GB × 1000. One GB is 10⁹ bytes and one MB is 10⁶ bytes, so the ratio is exactly 1000.
1024 is the binary step between GiB and MiB. MimiFile keeps GB/MB decimal and GiB/MiB binary so storage conversions remain unambiguous.
Useful when a specification, map, recipe, technical document or device uses Megabyte while your source value is in Gigabyte.
