Convert Megabytes to Kilobytes
1 megabyte is 1,000 kB. One megabyte is exactly 1000 kilobytes.
One megabyte is 1000 kilobytes. To convert megabytes to kilobytes, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly one million bytes.

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

What are megabytes and kilobytes?
- Megabyte (MB)
- Exactly one million bytes. A file manager showing a smaller number for the same file is counting in mebibytes.
- 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.
