About converting Terabytes to Megabytes
Terabytes (TB) and Megabytes (MB) are both units of digital storage, so converting between them is a single multiplication: multiply your Terabytes figure by 1,000,000. Ten Terabytes comes to 10,000,000 Megabytes, and a hundred works out at 100,000,000 Megabytes.
Rule of thumb: going from Terabytes to Megabytes multiplies, so the figure always grows — one Terabyte is already 1,000,000 Megabytes. If your answer came out smaller, you have the conversion the wrong way round.
What is a Terabyte?
A terabyte is a trillion bytes, and it is the unit that makes the decimal-versus-binary confusion impossible to ignore: buy a 1 TB drive, plug it into Windows, and it reports roughly 931 GB. Nothing is missing and nobody has short-changed you — the manufacturer counted in decimal terabytes, as SI defines them and as this site does, while Windows divided by 1,024 three times and still wrote "GB" on the result. The honest label for what Windows shows is 931 GiB. macOS and Linux mostly report decimal now; Windows still does not.
What is a Megabyte?
A megabyte is a million bytes under the SI prefixes this site uses, though Windows will call 1,048,576 bytes a megabyte; the IEC name for that binary version is the mebibyte (MiB). The best illustration of how confused this all got is the 1.44 MB floppy disk, whose "MB" was neither one nor the other — it meant 1,024,000 bytes, a decimal thousand of binary kilobytes, and essentially nothing else has ever used that unit. Today the megabyte is the natural size of a photo, a song or a document.
To put both in perspective: a 1 TB drive shows up as about 931 GB in Windows, while a minute of MP3 audio is roughly a megabyte.
