One gibibyte per second is exactly 8.589934592 gigabits per second, so converting gibibytes 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.
Gigabit per second is the rate of standard wired Ethernet and the faster fibre tiers. 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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into gigabits per second, which is usually more useful than the bare number.
The formula
gibibytes per second- The amount you are converting, in gibibytes per second

Worked examples
4K video stream: 0.00291 GiB/s in gigabits per second
Take 4k video stream, roughly 0.00291 GiB/s. The conversion is a single multiplication — 0.00291 × 8.58993 — giving 0.0249967 Gbit/s. Because the relationship is proportional, doubling the input doubles the answer to 0.0499934 Gbit/s.
SD video stream: 0.000349 GiB/s in gigabits per second
At 0.000349 GiB/s (sd video stream), the same quantity in gigabits per second is 0.000349 × 8.58993 = 0.00299789 Gbit/s. One gibibyte per second is 8.58993 gigabits per second, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many gigabits per second are in one gibibyte per second?
Exactly 8.589934592. 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 gigabits per second?
gigabits per second = gibibytes per second × 8.589934592. Reversed, gibibytes per second = gigabits per second ÷ 8.589934592, which is the same as multiplying by 0.116415321827.
Which is the bigger unit, the gibibyte per second or the gigabit per second?
The gibibyte per second. One gibibyte per second equals 8.58993 gigabits 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 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 GiB/s to Gbit/s in my head?
Plenty of people do this in their head: multiply by 8.6 instead of using the exact factor 8.589934592. At 100 that shortcut gives 860 gigabits per second, off by 1.007 gigabits per second or about 0.12%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
