1 terabyte (TB) = 1,000,000 megabytes (MB). To convert, multiply by 1,000,000: MB = TB × 1,000,000. For example, 5 TB = 5,000,000 MB.
MB = TB × 1,000,000

The two units
Terabyte (TB). One trillion bytes.
Megabyte (MB). One million bytes. Windows shows sizes in units of 1,048,576 bytes but labels them MB.
Because both units are defined in terms of the same base unit, the factor 1,000,000 is exact, not a rounded measurement.
