100 KB to MB
100 kilobytes to megabytes
Decimal (SI) — what most people mean
100 KB = 0.1 MB
Binary (IEC): 100 KB = 0.0977 MB
In the decimal standard (used by storage makers and Google), 1 KB = 1000 of the next unit down, so 100 KB = 0.1 MB. Operating systems use the binary standard (×1024), giving 0.0977 MB.

Frequently asked questions
How many megabytes is 100 KB?+
100 KB equals 0.1 MB using the decimal (SI) standard that drive makers and Google use, or 0.0977 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.
