A megabyte is one million bytes (10⁶) in the decimal convention. A typical phone photo is 2–5 MB and a minute of MP3 music about 1 MB.
Symbol: MB
Quantity: amount of digital information
SI relation: 1 MB = 8000000 bit (exact)

Exact: yes, by definition
Typical uses
- Photos, documents and songs
- Email attachment limits
- Mobile data usage
