About this conversion
This page converts kilobytes (KB), a decimal (SI) unit of digital storage equal to 1,000 bytes, or 8,000 bits, into megabytes (MB), a decimal unit of digital storage equal to 1,000 kilobytes, or 10^6 bytes.
This conversion is used constantly when checking file sizes, storage drive and memory capacity, network bandwidth, and mobile or broadband data plan allowances.
The formula is MB = KB × 0.001, based on the fixed relationship between these two digital storage units.
It's exact under the decimal (SI) definitions used here, where each decimal storage prefix is a fixed factor of 1,000 from the next (and bytes are a fixed factor of 8 from bits).
Digital storage prefixes follow the International System of Units (SI) for decimal units and the International Electrotechnical Commission (IEC) recommendations for binary units, keeping decimal and binary quantities unambiguous.
