What are kilobytes and megabytes?
A kilobyte is 1,000 bytes (decimal), a common unit for small files. A megabyte is one million bytes, roughly a minute of MP3 audio. For scale: a photo is a few MB, an HD movie a few GB, and a modern drive holds 1 TB or more. These use decimal (1 KB = 1,000 bytes).
How to convert kilobytes to megabytes
1 KB = 0.001 MB. To convert, multiply the number of kilobytes by 0.001. For example, 5 KB = 0.005 MB, and 20 KB = 0.02 MB. To go the other way, multiply megabytes by 1,000 (since 1 MB = 1,000 KB).
