About Gigabytes to Megabytes
Convert gigabytes to megabytes instantly, with a reference table of common values. The factor is exact: 1 GB = 1024 MB.
Needed when a plan or drive quoted in gigabytes has to be compared against individual file sizes, which are almost always listed in megabytes.
A gigabyte is a thousand megabytes. At this scale the divergence between the decimal and binary conventions reaches about 7%, which is why storage devices consistently appear smaller than the number printed on the box. It is the standard unit for device storage, memory capacity and monthly data plans. An hour of high-definition video is roughly 3 GB, and a modern phone typically holds 128 to 512 GB.
Worked through with real numbers: 1 GB is 1024 MB, 8 GB is 8192 MB, 64 GB is 65536 MB.
As for the other side of the conversion: A high-quality photograph is 3 to 8 MB, and a typical music track is about 5 MB.
Digital storage has two competing conventions. The SI definition makes a kilobyte 1,000 bytes; the binary convention used by much software makes it 1,024, properly called a kibibyte. The gap compounds at every step, reaching about 10% by the terabyte โ which is why a drive sold as 1 TB shows as roughly 931 GB.
