How to convert kilobytes to megabytes
MB = kB × 0.001Multiply the value in kilobytes by 0.001. To go the other way, multiply by 1,000 (or divide by 0.001).
A kilobyte is smaller than a megabyte: it takes 1,000 kilobytes to make one megabyte.

About the units
Kilobyte (kB)
1,000 bytes (decimal). Some software still uses “KB” for 1,024 bytes; that is properly a kibibyte (KiB). One kilobyte equals 8,000 bits (b).
Megabyte (MB)
1,000,000 bytes (decimal). A minute of MP3 audio is about 1 MB. One megabyte equals 8,000,000 bits (b).
Frequently asked questions
How many megabytes are in one kilobyte?
There are 0.001 megabytes in one kilobyte, and this value is exact by definition.
How do I convert kilobytes to megabytes?
Multiply the number of kilobytes by 0.001. For example, 10 kB × 0.001 = 0.01 MB.
How many kilobytes are in one megabyte?
One megabyte equals 1,000 kilobytes. That is the reverse factor, 1 ÷ 0.001.
What is 10 kilobytes in megabytes?
10 kB = 0.01 MB.
Is this kB to MB converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
