1 kilobyte (kB) = 0.001 megabytes (MB). To convert, divide by 1,000: MB = kB ÷ 1,000. For example, 500 kB = 0.5 MB.
MB = kB ÷ 1,000

The two units
Kilobyte (kB). 1,000 bytes in the SI sense. Some software uses "KB" for 1,024 bytes, which is properly a kibibyte (KiB).
Megabyte (MB). One million bytes. Windows shows sizes in units of 1,048,576 bytes but labels them MB.
Because both units are defined in terms of the same base unit, the factor 0.001 is exact, not a rounded measurement.
