One bit per second is exactly 1.192092896e-07 mebibytes per second, so converting bits per second to mebibytes per second is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
One bit per second is the base unit of data rate. Network speeds are always quoted in bits, which is why a 100 Mbps line downloads at about 12 MB/s. 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.
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. Below the calculator there is a step table for the values people look up most, and a second table putting real how much data moves per second figures into mebibytes per second so the number you get has something to be compared against.

Worked examples
HD video stream: 8e+06 bit/s in mebibytes per second
Take hd video stream, roughly 8e+06 bit/s. The conversion is a single multiplication — 8e+06 × 1.19209e-07 — giving 0.953674 MiB/s. Because the relationship is proportional, doubling the input doubles the answer to 1.90735 MiB/s.
MP3 audio, 320 kbps: 3.2e+05 bit/s in mebibytes per second
MP3 audio, 320 kbps comes to about 3.2e+05 bit/s. Multiplying by the factor: 3.2e+05 × 1.19209e-07 = 0.038147 MiB/s. Dividing the answer back by 1.19209e-07 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many mebibytes per second are in one bit per second?
Exactly 1.19209289551e-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 bits per second to mebibytes per second?
mebibytes per second = bits per second × 1.19209289551e-07. Reversed, bits per second = mebibytes per second ÷ 1.19209289551e-07, which is the same as multiplying by 8,388,608.
Which is the bigger unit, the bit per second or the mebibyte per second?
The mebibyte per second. One bit per second is only 1.19209e-07 of a mebibyte per second, so it takes 8.38861e+06 bits 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 bit per second?
One bit per second is the base unit of data rate. Network speeds are always quoted in bits, which is why a 100 Mbps line downloads at about 12 MB/s.
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.
Is there a quick way to do bit/s to MiB/s in my head?
Plenty of people do this in their head: divide by 8400000.000000 instead of using the exact factor 0.000000. At 100 that shortcut gives 0.000012 mebibytes per second, off by 1.6167e-08 mebibytes per second or about 0.14%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
