512 kilobytes to megabytes
Decimal (SI) — what most people mean
512 KB = 0.512 MB
Binary (IEC): 512 KB = 0.5 MB
In the decimal standard (used by storage makers and Google), 1 KB = 1000 of the next unit down, so 512 KB = 0.512 MB. Operating systems use the binary standard (×1024), giving 0.5 MB.

Frequently asked questions
How many megabytes is 512 KB?+
512 KB equals 0.512 MB using the decimal (SI) standard that drive makers and Google use, or 0.5 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.
