FAQ

How many kilobytes are in a megabyte?

1,024 KB, which is 1,024 × 1,024 = 1,048,576 bytes. That is the binary megabyte used by operating systems and by this converter; the decimal megabyte of the SI is 1,000 KB instead, and the IEC name for the binary one is the mebibyte (MiB).

What is the formula to convert kilobytes to megabytes?

Divide the kilobyte value by 1,024: 1,024 KB = 1 MB, 5,120 KB = 5 MB and 102,400 KB = 100 MB. Multiplying by 1,024 takes you back from megabytes to kilobytes.

Why does a 1 TB drive show up as about 931 GB?

Because the label and the operating system count on different scales. The manufacturer sells 1 TB as 1,000,000,000,000 bytes, while Windows divides that by 1,024 three times and prints 931 GB. No space disappears — it is the same number of bytes under two naming schemes, and this converter uses the binary one.
