One mebibyte per second is exactly 0.0009765625 gibibytes per second, so converting mebibytes per second to gibibytes 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.
Gibibytes per second is the binary counterpart of GB/s, 7.4% larger. 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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into gibibytes 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
0.0009765625- The exact number of gibibytes per second in one mebibyte per second

Worked examples
HD video stream: 0.954 MiB/s in gibibytes per second
Take hd video stream, roughly 0.954 MiB/s. The conversion is a single multiplication — 0.954 × 0.000976562 — giving 0.000931641 GiB/s. Because the relationship is proportional, doubling the input doubles the answer to 0.00186328 GiB/s.
SD video stream: 0.358 MiB/s in gibibytes per second
Take sd video stream, roughly 0.358 MiB/s. The conversion is a single multiplication — 0.358 × 0.000976562 — giving 0.000349609 GiB/s. Because the relationship is proportional, doubling the input doubles the answer to 0.000699219 GiB/s.

Frequently asked questions
How many gibibytes per second are in one mebibyte per second?
Exactly 0.0009765625. 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 gibibytes per second?
gibibytes per second = mebibytes per second × 0.0009765625. Reversed, mebibytes per second = gibibytes per second ÷ 0.0009765625, which is the same as multiplying by 1024.
Which is the bigger unit, the mebibyte per second or the gibibyte per second?
The gibibyte per second. One mebibyte per second is only 0.000976562 of a gibibyte per second, so it takes 1024 mebibytes per second to make one gibibyte 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 gibibyte per second?
Gibibytes per second is the binary counterpart of GB/s, 7.4% larger.
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 GiB/s in my head?
Plenty of people do this in their head: divide by 1000 instead of using the exact factor 0.0009765625. At 100 that shortcut gives 0.1 gibibytes per second, off by 0.002344 gibibytes per second or about 2.40%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
