This page converts mebibytes per second into kibibytes per second using the factor 1024, 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. A kibibyte is exactly 1,024 bytes. Linux tools and torrent clients often report KiB/s while marketing uses kB/s, a 2.4% difference.
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 kibibytes 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
1024- The exact number of kibibytes per second in one mebibyte per second
kibibytes per second- The converted result
How it works, step by step
- Enter the value in mebibytes per second.
- It is multiplied by 1024, the exact factor between the two units.
- The answer is shown in kibibytes 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 kibibytes per second
At 0.0381 MiB/s (mp3 audio, 320 kbps), the same quantity in kibibytes per second is 0.0381 × 1024 = 39.0144 KiB/s. One mebibyte per second is 1024 kibibytes per second, so the numbers grow as expected.
HD video stream: 0.954 MiB/s in kibibytes per second
At 0.954 MiB/s (hd video stream), the same quantity in kibibytes per second is 0.954 × 1024 = 976.896 KiB/s. One mebibyte per second is 1024 kibibytes per second, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many kibibytes per second are in one mebibyte per second?
Exactly 1024. 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 kibibytes per second?
kibibytes per second = mebibytes per second × 1024. Reversed, mebibytes per second = kibibytes per second ÷ 1024, which is the same as multiplying by 0.0009765625.
Which is the bigger unit, the mebibyte per second or the kibibyte per second?
The mebibyte per second. One mebibyte per second equals 1024 kibibytes 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 kibibyte per second?
A kibibyte is exactly 1,024 bytes. Linux tools and torrent clients often report KiB/s while marketing uses kB/s, a 2.4% difference.
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 KiB/s in my head?
Plenty of people do this in their head: multiply by 1000 instead of using the exact factor 1024. At 100 that shortcut gives 100,000 kibibytes per second, off by 2400 kibibytes per second or about 2.34%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
