One mebibyte per second is exactly 8388.608 kilobits per second, so converting mebibytes per second to kilobits 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.
Kilobits per second is the unit of audio bitrates and the old modem speeds. In networking a kilobit is exactly 1,000 bits, not 1,024. 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 kilobits per second so the number you get has something to be compared against.
The formula
mebibytes per second- The amount you are converting, in mebibytes per second
8388.608- The exact number of kilobits per second in one mebibyte per second
kilobits per second- The converted result
How it works, step by step

Worked examples
Wired gigabit Ethernet: 119 MiB/s in kilobits per second
Take wired gigabit ethernet, roughly 119 MiB/s. The conversion is a single multiplication — 119 × 8388.61 — giving 998,244 kbit/s. Because the relationship is proportional, doubling the input doubles the answer to 1.99649e+06 kbit/s.
4K video stream: 2.98 MiB/s in kilobits per second
4K video stream comes to about 2.98 MiB/s. Multiplying by the factor: 2.98 × 8388.61 = 24,998.1 kbit/s. Dividing the answer back by 8388.61 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 kilobits per second are in one mebibyte per second?
Exactly 8388.608. 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 kilobits per second?
kilobits per second = mebibytes per second × 8388.608. Reversed, mebibytes per second = kilobits per second ÷ 8388.608, which is the same as multiplying by 0.000119209289551.
Which is the bigger unit, the mebibyte per second or the kilobit per second?
The mebibyte per second. One mebibyte per second equals 8388.61 kilobits 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 kilobit per second?
Kilobits per second is the unit of audio bitrates and the old modem speeds. In networking a kilobit is exactly 1,000 bits, not 1,024.
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 kbit/s in my head?
Plenty of people do this in their head: multiply by 8400 instead of using the exact factor 8388.608. At 100 that shortcut gives 840,000 kilobits per second, off by 1139 kilobits per second or about 0.14%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
