- 1 Megabytes (MB) = 1000 Kilobytes (kB)
Convert megabytes to kilobytes using the decimal standard, useful when a file size or data cap is in MB but you need it in KB. Enter the megabytes and read the kilobytes, and swap for the reverse. Binary units (KiB, MiB) are available if you need powers of 1024.
How this is calculated
This uses the decimal SI standard where 1 MB is 1000 kB and 1 kB is 1000 bytes, the convention used by storage makers and networks. Binary units in the list use powers of 1024 instead, so 1 MiB is 1024 KiB.
How to use
- Enter the size in megabytes.
- Keep MB to KB, or press Swap for the reverse.
- Read the result in kilobytes.
Examples
- One megabyte:
1 MB = 1,000 kB - Five megabytes:
5 MB = 5,000 kB
FAQ
- How many KB are in a MB?
- In the decimal standard used here, 1000 kilobytes make one megabyte. In binary units, 1 MiB is 1024 KiB.
- Why do decimal and binary units differ?
- Storage and network specs use decimal (1000), while operating systems often report binary (1024). This tool defaults to decimal but includes binary units.
