Megabytes (MB) to Kilobytes (kB) Conversion
Megabytes
The megabyte (MB) is a unit of digital information equal to 1,000,000 bytes (10⁶ bytes) in the SI decimal definition, or 1,048,576 bytes in binary convention. A minute of CD-quality audio requires approximately 10 MB uncompressed; a typical JPEG photograph ranges from 2 to 8 MB; a standard definition video runs roughly 1 GB per hour. The megabyte was the dominant storage unit for personal computers throughout the 1980s and 1990s before the gigabyte became standard.
Kilobytes
The kilobyte (kB) is a unit of digital information equal to 1,000 bytes in the SI decimal system. In the binary convention historically used by operating systems, 1,024 bytes was called a kilobyte — now formally named a kibibyte (KiB). Hard drive manufacturers use the decimal definition, while operating systems historically used binary values, making a "500 GB" drive appear as roughly 465 GB in Windows. Plain-text documents, small images, and configuration files are measured at the kilobyte scale.
