One mebibyte per second is exactly 0.008388608 gigabits per second, so converting mebibytes per second to gigabits 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.
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. Gigabit per second is the rate of standard wired Ethernet and the faster fibre tiers.
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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in gigabits per second, so you can sanity-check whether your answer is a plausible size.
The formula
mebibytes per second- The amount you are converting, in mebibytes per second
0.008388608- The exact number of gigabits per second in one mebibyte per second
gigabits per second- The converted result
How it works, step by step
- Enter the value in mebibytes per second.
- It is multiplied by 0.008388608, the exact factor between the two units.
- The answer is shown in gigabits per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
SD video stream: 0.358 MiB/s in gigabits per second
SD video stream comes to about 0.358 MiB/s. Multiplying by the factor: 0.358 × 0.00838861 = 0.00300312 Gbit/s. Dividing the answer back by 0.00838861 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
MP3 audio, 320 kbps: 0.0381 MiB/s in gigabits per second
MP3 audio, 320 kbps comes to about 0.0381 MiB/s. Multiplying by the factor: 0.0381 × 0.00838861 = 0.000319606 Gbit/s. Dividing the answer back by 0.00838861 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 gigabits per second are in one mebibyte per second?
Exactly 0.008388608. 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 gigabits per second?
gigabits per second = mebibytes per second × 0.008388608. Reversed, mebibytes per second = gigabits per second ÷ 0.008388608, which is the same as multiplying by 119.209289551.
Which is the bigger unit, the mebibyte per second or the gigabit per second?
The gigabit per second. One mebibyte per second is only 0.00838861 of a gigabit per second, so it takes 119.209 mebibytes per second to make one gigabit 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 gigabit per second?
Gigabit per second is the rate of standard wired Ethernet and the faster fibre tiers.
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 Gbit/s in my head?
Plenty of people do this in their head: divide by 120 instead of using the exact factor 0.008388608. At 100 that shortcut gives 0.83333333 gigabits per second, off by 0.005527 gigabits per second or about 0.66%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
