Convert Kilobytes to Megabytes

1 kilobyte is 0.001 MB. One kilobyte is exactly 0.001 megabytes.

One kilobyte is 0.001 megabytes. To convert kilobytes to megabytes, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly 1,000 bytes under the SI prefix, which is what drive manufacturers and network speeds use.

Factors are entered by hand from IEC 80000-13 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert kilobytes to megabytes?

  1. 1.Take the measurement in kilobytes.
  2. 2.Multiply by 0.001 — that is how many megabytes fit in one kilobyte.
  3. 3.To go back the other way, divide by 0.001, or multiply by 1000.

What are kilobytes and megabytes?

Kilobyte (kB)
Exactly 1,000 bytes under the SI prefix, which is what drive manufacturers and network speeds use. Not 1,024 — that is the kibibyte.
Megabyte (MB)
Exactly one million bytes. A file manager showing a smaller number for the same file is counting in mebibytes.
