This page converts bytes per second into mebibytes per second using the factor 9.536743164e-07, 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. One byte per second is eight bits per second. File transfer tools report bytes, which is the single most common source of confusion about whether a connection is running at its rated speed.
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 mebibytes per second, which is usually more useful than the bare number.
The formula
bytes per second- The amount you are converting, in bytes per second
9.53674316406e-07- The exact number of mebibytes per second in one byte per second
mebibytes per second- The converted result
How it works, step by step
- Enter the value in bytes per second.
- It is multiplied by 9.53674316406e-07, the exact factor between the two units.
- The answer is shown in mebibytes per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
4K video stream: 3.12e+06 B/s in mebibytes per second
At 3.12e+06 B/s (4k video stream), the same quantity in mebibytes per second is 3.12e+06 × 9.53674e-07 = 2.97546 MiB/s. One byte per second is 9.53674e-07 mebibytes per second, so the numbers shrink as expected.
MP3 audio, 320 kbps: 4e+04 B/s in mebibytes per second
MP3 audio, 320 kbps comes to about 4e+04 B/s. Multiplying by the factor: 4e+04 × 9.53674e-07 = 0.038147 MiB/s. Dividing the answer back by 9.53674e-07 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
How to read your score
Frequently asked questions
How many mebibytes per second are in one byte per second?
Exactly 9.53674316406e-07. 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 bytes per second to mebibytes per second?
mebibytes per second = bytes per second × 9.53674316406e-07. Reversed, bytes per second = mebibytes per second ÷ 9.53674316406e-07, which is the same as multiplying by 1,048,576.
Which is the bigger unit, the byte per second or the mebibyte per second?
The mebibyte per second. One byte per second is only 9.53674e-07 of a mebibyte per second, so it takes 1.04858e+06 bytes per second to make one mebibyte 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 byte per second?
One byte per second is eight bits per second. File transfer tools report bytes, which is the single most common source of confusion about whether a connection is running at its rated speed.
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.
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.
