MB to GB Converter

Summarize files or quotas in a larger unit while making the prefix convention explicit. Decimal SI is the default for MB and GB; IEC Binary mode uses MiB and GiB instead.

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.

From Many Megabytes To Gigabytes

Decimal mode uses GB = MB / 1000. Binary mode uses GiB = MiB / 1024. For example, 1000 MB is 1 GB, while 1024 MiB is 1 GiB.

A Quota Is More Than A Unit Conversion

The result does not include filesystem overhead, reserved space, compression, redundancy, provider billing rules, or upload policy. Check the system that owns the quota before making a capacity decision.
