500 GB to MB
500 gigabytes to megabytes
Decimal (SI) — what most people mean
500 GB = 500000 MB
Binary (IEC): 500 GB = 512000 MB
In the decimal standard (used by storage makers and Google), 1 GB = 1000 of the next unit down, so 500 GB = 500000 MB. Operating systems use the binary standard (×1024), giving 512000 MB.

Frequently asked questions
How many megabytes is 500 GB?+
500 GB equals 500000 MB using the decimal (SI) standard that drive makers and Google use, or 512000 MB using the binary standard that operating systems use.
Why are there two answers?+
Storage is measured two ways: decimal (1 MB = 1000 of the next unit down) and binary (1 MB = 1024). Hard-drive and SSD capacities are advertised in decimal, while Windows and other systems report sizes in binary — which is why a "1 TB" drive shows as about 931 GB in your operating system.
