How many MB is 1TB?

[Calvados]

Can anyone advise on this please?

[Graham-W]

1 TB is 1,000,000 Mb or 1,000 Gigabytes.

[sunny-dave]

Accurately speaking it should b 1024 x 1024 MB in a TB (which is 1,048,576).

In common usage though it often seems to be taken that 1000 MB = 1GB and 1000GB = 1TB, so 1TB = 1,000,000 MB

strictly speaking 1 terabyte = 1,048,576 megabytes but a million is near enough for most purposes

Thank you

Both sunny-dave and jno have given incorrect answers. Their answers are a very common misunderstanding.

Kilo, Mega, Giga and Tera are standard SI scale factors of 1000, 1,000,000, 1,000,000,000 and 1,000,000,000,000 respectively.

These are the factors used in designation of the number of bytes on a disk drive.

Windows reports files sizes in kibibytes and mibibytes which use scales of 1024 (2^10) and 1,048,576 (2^20) respectively. Similarly upwards with gibibytes and tibibytes.

This is why the disk size in Windows appears to be substantially less than the manufacturer's specification.

It makes very little difference at the Kilo vs kibi level but the difference between a tibibyte and a Terabye is nearly ten percent because of the exponential nature of the difference.
