Multiply MB by 0.001 to get GB. The displayed factor is rounded; the calculator uses the full stored conversion factor.
Decimal storage units use 1 GB = 1,000 MB. For binary memory units, choose MiB and GiB, where the factor is 1,024.
Worked example
1,000 MB = 1 GB. To reverse it, enter the unrounded output and select Swap units. Round only the final result; converting an already-rounded result back may not reproduce the original exactly.
