Definition: A KB (kilobyte) is about 1,000 bytes. A (MB) megabyte is equal to about 1,000KB.
A kilobyte is a method of measuring the size of computer files, including digital photo files. Photos with more detail and image quality are larger files, requiring more computer storage space. Most digital photos require more than 1,000KB, or 1MB, of storage space.
A megabyte is different from a megapixel (MP).
