Formula

How to convert Terabytes to Megabytes

To convert terabytes to megabytes, multiply by 1,048,576. One terabyte equals 1,048,576 MB, and one megabyte equals 9.53674 × 10⁻⁷ TB.

  1. Take the value in terabytes — for example 3 TB.
  2. Multiply by 1,048,576 (the number of megabytes in one terabyte).
  3. 3 × 1,048,576 = 3,145,728 MB.

About converting Terabytes to Megabytes

Terabytes (TB) and Megabytes (MB) are both units of data storage. The exact factor is 1 TB = 1,048,576 MB, so multiply by 1,048,576 to go from terabytes to megabytes (or divide to go back).

The conversion runs entirely in your browser. Need the reverse? Use the Megabytes to Terabytes converter, or the full unit converter for every unit at once.

Binary vs decimal: why your drive looks smaller

Windows and RAM reports count in powers of 1,024 (binary, sometimes written KiB/MiB/GiB); drive makers, macOS and mobile carriers count in powers of 1,000 (decimal). Same bytes, two answers:

Example: a “1 TB” drive holds 10¹² bytes, which Windows shows as about 931 GB.

The units

Terabytes (TB)

Here, 1,024 GB = 1,099,511,627,776 bytes (TiB). Decimal terabyte = 10¹² bytes.

Used for: Hard drives and cloud storage.

Megabytes (MB)

Here, 1,024 KB = 1,048,576 bytes (MiB). Decimal megabyte = 1,000,000 bytes.

Used for: Photos, songs, app downloads.

This page uses binary units (1 KB = 1,024 bytes), which is how Windows and most RAM reports count. Storage makers and macOS use decimal units (1 kB = 1,000 bytes), so both are shown below.
