Quick answer
1 TB = 1,000,000 MB (decimal) and 1 TiB = 1,048,576 MiB (binary). To convert MB to TB, divide by 1,000,000. To convert MiB to TiB, divide by 1,048,576. Example: 2,500,000 MB = 2.5 TB, while 2,500,000 MiB is about 2.384186 TiB.
How to convert MB to TB
TB = MB ÷ 1,000,000. TiB = MiB ÷ 1,048,576 (1,024 × 1,024). Megabyte to terabyte is two prefix steps, so the divisor is the single-step factor squared. For one step at a time, use the MB to GB converter and then the GB to TB converter. To go the other way, use the TB to MB converter.
- 500,000 MB is 0.5 TB decimal. As MiB, 500,000 is about 0.476837 TiB.
- 1,000,000 MB is exactly 1 TB. As MiB, it is about 0.953674 TiB.
- 1,048,576 MiB is exactly 1 TiB. As MB, it is 1.048576 TB.
- Fast estimate: move the decimal point six places left. 3,800,000 MB is about 3.8 TB.

Frequently asked questions
How many MB make 1 TB?
1 TB = 1,000,000 MB in decimal units. 1 TiB = 1,048,576 MiB in binary units.
How do I convert MB to TB?
Divide the megabytes by 1,000,000 for decimal terabytes, or by 1,048,576 for binary tebibytes. 5,000,000 MB = 5 TB.
Is 1,000,000 MB equal to 1 TB?
Yes in decimal units. In binary units, 1,048,576 MiB is exactly 1 TiB, and 1,000,000 MiB is about 0.953674 TiB.
How many TB is 500,000 MB?
500,000 MB = 0.5 TB in decimal, or about 0.476837 TiB in binary.
How many TB is 1 GB?
1 GB = 0.001 TB in decimal units. See the GB to TB converter.
Why is the binary answer smaller?
A tebibyte is larger than a terabyte (1,099,511,627,776 bytes against 1,000,000,000,000), so the same number of bytes is fewer TiB than TB.
What is the formula for MB to TB?
Divide the megabytes by 1,000,000. For mebibytes, divide by 1,048,576 to get tebibytes.
Does this converter upload my numbers?
No. The conversion runs in your browser with exact integer arithmetic, so nothing you type leaves the page.
