- Typing in the Terabytes field converts back to Megabytes the same way.
- Use the reference table for the values that come up most often.
Megabytes to Terabytes formula
Converting megabytes to terabytes is a single multiplication by 1e-06.
TB = MB × 1e-06
Why this factor: the megabyte and the terabyte are both defined against the byte, so dividing one definition by the other gives 1e-06 directly. Both definitions are set out in full below.
To go the other way, divide by 1e-06 — or use the Terabytes to Megabytes converter, which is the same calculation reversed.
Worked example
Take 500 MB and multiply by the factor 1e-06: the result is 0.0005 TB.
500 MB × 1e-06 = 0.0005 TB
The converter above does this for any value you type, in either direction.
What is a megabyte?
A megabyte is one million bytes, the familiar unit for photos, songs and app sizes.
Definition: Exactly 1,000,000 bytes under SI prefixes. The binary mebibyte (MiB) is 1,048,576 bytes.
Where it is used: Photo and audio file sizes, app downloads, and mobile data allowances.
What is a terabyte?
A terabyte is one trillion bytes, the standard capacity unit for hard drives and large archives.
Definition: Exactly 1×10¹² bytes under SI prefixes. The binary tebibyte (TiB) is about 1.1×10¹² bytes.
Where it is used: Hard drive and SSD capacity, backup archives, and database sizes.
Worth knowing: A 1 TB drive reports as roughly 931 GiB in an operating system that counts in powers of two — the storage is not missing, just labelled differently.
Megabytes vs Terabytes
The megabyte and the terabyte belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
Frequently asked questions
How many terabytes are in a megabyte?
