Megabyte
- Megabyte
- A megabyte is a unit of storage, often abbreviated to simply MB
meaning a million bytes.
Strictly, 1 megabyte = 2 to the twentieth power (220) bytes = 1,048,576 bytes = 1024 kilobytes. See also gigabyte.
Computer memory (RAM) is normally measured in megabytes, as is disk space.
Note: Storage devices sold by manufacturers normally assume 1MB = 1,000,000 bytes.
