How Many Megabytes in a Gigabyte?
Quick Answer
There are 1,000 megabytes in a gigabyte (GB) using the SI standard, or 1,024 mebibytes in a gibibyte (GiB) using the binary standard.
1 GB = 1,000 MB (SI) or 1 GiB = 1,024 MiB (binary)
Understanding the Conversion
In the SI (decimal) standard used by storage manufacturers, one gigabyte (GB) equals exactly 1,000 megabytes. In the binary standard used by operating systems, one gibibyte (GiB) equals 1,024 mebibytes (MiB). Most consumers encounter the SI standard when buying storage devices.
Formula
1 GB = 1,000 MB (SI) or 1 GiB = 1,024 MiB (binary)
