How many bytes are roughly in a megabyte (MB)?

A megabyte (MB) is defined as roughly one million bytes. More precisely, in the binary system that is often used in computing, one megabyte is equal to 1,024 kilobytes, and one kilobyte is equal to 1,024 bytes, which results in 1,024 x 1,024 = 1,048,576 bytes. However, for practical purposes and simplicity, the metric definition of one megabyte being approximately one million bytes is widely accepted and commonly used. This understanding is essential for grasping data sizes as they relate to storage capacity and file sizes in computing.
