1000 KB to MB
1000 kilobytes to megabytes
Decimal (SI) — what most people mean
1000 KB = 1 MB
Binary (IEC): 1000 KB = 0.9766 MB
In the decimal standard (used by storage makers and Google), 1 KB = 1000 of the next unit down, so 1000 KB = 1 MB. Operating systems use the binary standard (×1024), giving 0.9766 MB.

Frequently asked questions
How many megabytes is 1000 KB?+
1000 KB equals 1 MB using the decimal (SI) standard that drive makers and Google use, or 0.9766 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.
