This page converts gigabits per second into kibibytes per second using the factor 122,070.3125, 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 kibibyte is exactly 1,024 bytes. Linux tools and torrent clients often report KiB/s while marketing uses kB/s, a 2.4% difference. 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. Below the calculator there is a step table for the values people look up most, and a second table putting real how much data moves per second figures into kibibytes per second so the number you get has something to be compared against.
The formula
gigabits per second- The amount you are converting, in gigabits per second

Worked examples
HD video stream: 0.008 Gbit/s in kibibytes per second
HD video stream comes to about 0.008 Gbit/s. Multiplying by the factor: 0.008 × 122,070 = 976.562 KiB/s. Dividing the answer back by 122,070 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
4K video stream: 0.025 Gbit/s in kibibytes per second
4K video stream comes to about 0.025 Gbit/s. Multiplying by the factor: 0.025 × 122,070 = 3051.76 KiB/s. Dividing the answer back by 122,070 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 kibibytes per second are in one gigabit per second?
Exactly 122,070.3125. 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 kibibytes per second?
kibibytes per second = gigabits per second × 122,070.3125. Reversed, gigabits per second = kibibytes per second ÷ 122,070.3125, which is the same as multiplying by 8.192e-06.
Which is the bigger unit, the gigabit per second or the kibibyte per second?
The gigabit per second. One gigabit per second equals 122,070 kibibytes 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 kibibyte per second?
A kibibyte is exactly 1,024 bytes. Linux tools and torrent clients often report KiB/s while marketing uses kB/s, a 2.4% difference.
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 KiB/s in my head?
Plenty of people do this in their head: multiply by 120,000 instead of using the exact factor 122,070.3125. At 100 that shortcut gives 12,000,000 kibibytes per second, off by 207031.250000 kibibytes per second or about 1.70%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
