Unit definitions

What is a megabyte?

The megabyte (decimal) is one million bytes (1000²) under the SI convention. Photos, songs, and documents are commonly sized in megabytes. It differs from the mebibyte, which is 1,048,576 bytes.

What is a kibibyte?

The kibibyte is exactly 1024 bytes (2¹⁰) under the IEC binary convention. It removes the ambiguity of the older 'kilobyte = 1024 bytes' usage in operating systems. Memory sizes are naturally expressed in binary units like this.
