To convert gigabits per second to mebibytes per second, multiply by 119.2092896. That factor is the whole relationship: both units measure how much data moves per second, so the conversion is a proportion with no offset and no substance-specific constant.
Gigabit per second is the rate of standard wired Ethernet and the faster fibre tiers. 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 mebibytes per second, which is usually more useful than the bare number.
The formula
gigabits per second- The amount you are converting, in gigabits per second
119.209289551- The exact number of mebibytes per second in one gigabit per second

Worked examples
Wi-Fi 6 link rate: 1.2 Gbit/s in mebibytes per second
At 1.2 Gbit/s (wi-fi 6 link rate), the same quantity in mebibytes per second is 1.2 × 119.209 = 143.051 MiB/s. One gigabit per second is 119.209 mebibytes per second, so the numbers grow as expected.
Wired gigabit Ethernet: 1 Gbit/s in mebibytes per second
Take wired gigabit ethernet, roughly 1 Gbit/s. The conversion is a single multiplication — 1 × 119.209 — giving 119.209 MiB/s. Because the relationship is proportional, doubling the input doubles the answer to 238.419 MiB/s.

Frequently asked questions
How many mebibytes per second are in one gigabit per second?
Exactly 119.209289551. 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 gigabits per second to mebibytes per second?
mebibytes per second = gigabits per second × 119.209289551. Reversed, gigabits per second = mebibytes per second ÷ 119.209289551, which is the same as multiplying by 0.008388608.
Which is the bigger unit, the gigabit per second or the mebibyte per second?
The gigabit per second. One gigabit per second equals 119.209 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 gigabit per second?
Gigabit per second is the rate of standard wired Ethernet and the faster fibre tiers.
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 Gbit/s to MiB/s in my head?
Plenty of people do this in their head: multiply by 120 instead of using the exact factor 119.2092896. At 100 that shortcut gives 12,000 mebibytes per second, off by 79.07 mebibytes per second or about 0.66%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
