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.Take the measurement in kilobytes.
- 2.Multiply by 0.001 — that is how many megabytes fit in one kilobyte.
- 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.
