To convert kilobits per second to gibibytes per second, multiply by 1.164153218e-07. 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.
Kilobits per second is the unit of audio bitrates and the old modem speeds. In networking a kilobit is exactly 1,000 bits, not 1,024. 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. 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 gibibytes per second so the number you get has something to be compared against.

Worked examples
4K video stream: 2.5e+04 kbit/s in gibibytes per second
At 2.5e+04 kbit/s (4k video stream), the same quantity in gibibytes per second is 2.5e+04 × 1.16415e-07 = 0.00291038 GiB/s. One kilobit per second is 1.16415e-07 gibibytes per second, so the numbers shrink as expected.
HD video stream: 8000 kbit/s in gibibytes per second
Take hd video stream, roughly 8000 kbit/s. The conversion is a single multiplication — 8000 × 1.16415e-07 — giving 0.000931323 GiB/s. Because the relationship is proportional, doubling the input doubles the answer to 0.00186265 GiB/s.
How to read your score
Frequently asked questions
How many gibibytes per second are in one kilobit per second?
Exactly 1.16415321827e-07. 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 kilobits per second to gibibytes per second?
gibibytes per second = kilobits per second × 1.16415321827e-07. Reversed, kilobits per second = gibibytes per second ÷ 1.16415321827e-07, which is the same as multiplying by 8,589,934.592.
Which is the bigger unit, the kilobit per second or the gibibyte per second?
The gibibyte per second. One kilobit per second is only 1.16415e-07 of a gibibyte per second, so it takes 8.58993e+06 kilobits 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 kilobit per second?
Kilobits per second is the unit of audio bitrates and the old modem speeds. In networking a kilobit is exactly 1,000 bits, not 1,024.
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 kbit/s to GiB/s in my head?
Plenty of people do this in their head: divide by 8600000.000000 instead of using the exact factor 0.000000. At 100 that shortcut gives 0.000012 gibibytes per second, off by 1.3625e-08 gibibytes per second or about 0.12%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
