ConverterGB to MB Converter
Break a gigabyte quantity into megabytes for a file budget, export estimate, or system report. The output remains decimal MB unless IEC Binary mode is deliberately selected.
Decimal SI is selected. Enter up to 120 significant digits using a decimal point or scientific notation with exponent magnitude no greater than 1000. Commas and negative quantities are rejected.
Expand Without Mixing Labels
Decimal SI uses MB = GB x 1000. IEC Binary uses MiB = GiB x 1024. The interface changes the labels, formula, and copy text together.
Displayed Capacity Can Differ
Applications may choose different display conventions for the same byte count. A number that looks different is not by itself evidence that storage disappeared; compare the byte count and unit definition.
Frequently Asked Questions
In Decimal SI, 1 GB equals 1000 MB. The binary relationship is 1 GiB equals 1024 MiB.
