This page converts mebibytes per second into terabits per second using the factor 8.388608e-06, and shows the reverse figure alongside it. Both units measure how much data moves per second, which is why one number does the whole job.
A mebibyte is 1,048,576 bytes, about 4.9% more than a megabyte. The gap is why a "100 MB/s" drive benchmarks at roughly 95 MiB/s. Terabits per second describes backbone and submarine cable capacity rather than anything you can buy for a house.
Bits and bytes. Network speeds are sold in bits per second and file transfers are reported in bytes per second, and there are eight bits to a byte, so a 100 Mbps line downloads at about 12 MB/s. A connection is not underperforming by a factor of eight; it is being measured in different units. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into terabits per second, which is usually more useful than the bare number.
The formula
mebibytes per second- The amount you are converting, in mebibytes per second
8.388608e-06- The exact number of terabits per second in one mebibyte per second
terabits per second- The converted result
How it works, step by step
- Enter the value in mebibytes per second.
- It is multiplied by 8.388608e-06, the exact factor between the two units.
- The answer is shown in terabits per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
MP3 audio, 320 kbps: 0.0381 MiB/s in terabits per second
At 0.0381 MiB/s (mp3 audio, 320 kbps), the same quantity in terabits per second is 0.0381 × 8.38861e-06 = 3.19606e-07 Tbit/s. One mebibyte per second is 8.38861e-06 terabits per second, so the numbers shrink as expected.
Wired gigabit Ethernet: 119 MiB/s in terabits per second
At 119 MiB/s (wired gigabit ethernet), the same quantity in terabits per second is 119 × 8.38861e-06 = 0.000998244 Tbit/s. One mebibyte per second is 8.38861e-06 terabits per second, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many terabits per second are in one mebibyte per second?
Exactly 8.388608e-06. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert mebibytes per second to terabits per second?
terabits per second = mebibytes per second × 8.388608e-06. Reversed, mebibytes per second = terabits per second ÷ 8.388608e-06, which is the same as multiplying by 119,209.289551.
Which is the bigger unit, the mebibyte per second or the terabit per second?
The terabit per second. One mebibyte per second is only 8.38861e-06 of a terabit per second, so it takes 119,209 mebibytes per second to make one terabit per second.
What does this quantity actually measure?
Both units measure how much data moves per second. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a mebibyte per second?
A mebibyte is 1,048,576 bytes, about 4.9% more than a megabyte. The gap is why a "100 MB/s" drive benchmarks at roughly 95 MiB/s.
What is a terabit per second?
Terabits per second describes backbone and submarine cable capacity rather than anything you can buy for a house.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do MiB/s to Tbit/s in my head?
Plenty of people do this in their head: divide by 120,000 instead of using the exact factor 0.000008. At 100 that shortcut gives 0.00083333333 terabits per second, off by 0.000006 terabits per second or about 0.66%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
