Convert Megabyte to Kilobyte
1 megabyte = 1,000 kilobyte (KB). For example, 10 megabyte = 10,000 kilobyte and 100 megabyte = 100,000 kilobyte. Type any value below to convert megabyte to kilobyte both ways — it runs entirely in your browser.
Megabyte to Kilobyte conversion formula
To convert megabyte to kilobyte, multiply by 1,000:
kilobyte = megabyte × 1,000
Going the other way, 1 kilobyte = 0.001 megabyte, so
megabyte = kilobyte × 0.001.

About megabyte and kilobyte
Megabyte: A megabyte is 1,000,000 bytes (decimal). The binary 1,048,576-byte unit is the mebibyte (MiB).
Kilobyte: A kilobyte is 1,000 bytes in the SI/decimal convention used by storage makers and networks. The 1,024-byte unit is the kibibyte (KiB).
This converter uses the decimal (SI) convention for KB/MB/GB/TB (1 KB = 1,000 bytes), as used by storage manufacturers and networks. The binary units — KiB, MiB, GiB (1 KiB = 1,024 bytes) — are listed separately, because operating systems often label binary sizes with the decimal names.
