This page converts gibibytes per second into mebibytes 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. Gibibytes per second is the binary counterpart of GB/s, 7.4% larger.
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 mebibytes per second, so you can sanity-check whether your answer is a plausible size.
The formula
gibibytes per second- The amount you are converting, in gibibytes per second
1024- The exact number of mebibytes per second in one gibibyte per second
mebibytes per second- The converted result
How it works, step by step
- Enter the value in gibibytes per second.
- It is multiplied by 1024, the exact factor between the two units.
- The answer is shown in mebibytes per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
4K video stream: 0.00291 GiB/s in mebibytes per second
At 0.00291 GiB/s (4k video stream), the same quantity in mebibytes per second is 0.00291 × 1024 = 2.97984 MiB/s. One gibibyte per second is 1024 mebibytes per second, so the numbers grow as expected.
Wi-Fi 6 link rate: 0.14 GiB/s in mebibytes per second
At 0.14 GiB/s (wi-fi 6 link rate), the same quantity in mebibytes per second is 0.14 × 1024 = 143.36 MiB/s. One gibibyte per second is 1024 mebibytes per second, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many mebibytes per second are in one gibibyte 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 gibibytes per second to mebibytes per second?
mebibytes per second = gibibytes per second × 1024. Reversed, gibibytes per second = mebibytes per second ÷ 1024, which is the same as multiplying by 0.0009765625.
Which is the bigger unit, the gibibyte per second or the mebibyte per second?
The gibibyte per second. One gibibyte per second equals 1024 mebibytes 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 gibibyte per second?
Gibibytes per second is the binary counterpart of GB/s, 7.4% larger.
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 GiB/s to MiB/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 mebibytes per second, off by 2400 mebibytes per second or about 2.34%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
