Terabyte to Megabyte formula
MB = TB × 1000000
Convert 5 terabytes to megabytes
- Start with 5 terabytes.
- Multiply by the conversion factor: 5 × 1,000,000 = 5,000,000.
- So 5 TB = 5,000,000 MB.

Unit definitions
What is a terabyte?
The terabyte (decimal) is one trillion bytes (1000⁴) under the SI convention. Modern hard drives and large media libraries are measured in terabytes. It differs from the binary tebibyte (1024⁴ bytes).
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.
