50 MB to KB
50 megabytes to kilobytes
Decimal (SI) — what most people mean
50 MB = 50000 KB
Binary (IEC): 50 MB = 51200 KB
In the decimal standard (used by storage makers and Google), 1 MB = 1000 of the next unit down, so 50 MB = 50000 KB. Operating systems use the binary standard (×1024), giving 51200 KB.

Frequently asked questions
How many kilobytes is 50 MB?+
50 MB equals 50000 KB using the decimal (SI) standard that drive makers and Google use, or 51200 KB using the binary standard that operating systems use.
Why are there two answers?+
Storage is measured two ways: decimal (1 KB = 1000 of the next unit down) and binary (1 KB = 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.
