Megabytes to Terabytes Converter

Megabytes to Terabytes

Convert megabytes (MB) to terabytes (TB). Both measure digital storage, and the conversion comes up in computing, storage, internet work.

The Formula

`` terabytes = megabytes × 0.000001 megabytes = terabytes × 1000000 `

One megabyte is 1.0000e-6 terabytes, and one terabyte is 1,000,000 megabytes.

Conversion Table

Megabytes	Terabytes
1 MB	1.0000e-6 TB
2 MB	2.0000e-6 TB
5 MB	5.0000e-6 TB
10 MB	1.0000e-5 TB
25 MB	2.5000e-5 TB
50 MB	5.0000e-5 TB
100 MB	1.0000e-4 TB
500 MB	5.0000e-4 TB
1,000 MB	0.001 TB

The Other Direction

Terabytes	Megabytes
1 TB	1,000,000 MB
2 TB	2,000,000 MB
5 TB	5,000,000 MB
10 TB	10,000,000 MB
25 TB	25,000,000 MB
50 TB	50,000,000 MB
100 TB	100,000,000 MB
500 TB	500,000,000 MB
1,000 TB	1,000,000,000 MB

What Each Unit Is

Megabytes (MB) — 1,000,000 bytes in decimal usage. The file-size unit of the CD-ROM era.

Terabytes (TB) — 1,000,000,000,000 bytes in decimal usage. The unit of consumer drives since the late 2000s.

A Sense of Scale

• An MP3 is 3–5 MB
• A phone photo is 2–5 MB
• A JS bundle should stay under 1 MB
• A 1 TB drive shows as 931 GiB in Windows
• A 4K film master is several TB

Precision

The factor 0.000001 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

In Code

`javascript const megabyteToTerabyte = (value) => value * 0.000001; ``

How Many Decimals Do You Need?

Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 MB with the factor truncated at each decimal place:

Decimals kept	Factor	137 MB becomes	Error
0	0	0	100.0000%
1	0	0	100.0000%
2	0	0	100.0000%
3	0	0	100.0000%
4	0	0	100.0000%

A rule that holds for any conversion: round once, at the end. Rounding the factor and then multiplying compounds the error through every subsequent calculation, while carrying full precision and rounding the final answer does not.

The right number of significant figures is set by your input, not by the converter. If you measured megabytes to three significant figures, the answer in terabytes is only good to three — writing more digits claims precision the measurement never had.

Other Conversions From Megabytes

The same value in every other unit this converter supports for data:

From	To	Unit
1 MB	8,000,000 b	Bits
1 MB	1,000,000 B	Bytes
1 MB	8,000 Kb	Kilobits
1 MB	1,000 KB	Kilobytes
1 MB	8 Mb	Megabits
1 MB	0.001 GB	Gigabytes

Chaining conversions works — megabytes to metres to feet gives the same answer as megabytes to feet — but each step rounds, so a chain of three conversions carries three roundings. Convert directly where a direct factor exists.
