To convert gibibytes per second to kilobytes per second, multiply by 1,073,741.824. 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.
Kilobytes per second is what a download dialog shows on a slow connection: 1 kB/s is 8 kbit/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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into kilobytes 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
1,073,741.824- The exact number of kilobytes per second in one gibibyte per second
kilobytes per second- The converted result

- It is multiplied by 1,073,741.824, the exact factor between the two units.
- The answer is shown in kilobytes per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Wired gigabit Ethernet: 0.116 GiB/s in kilobytes per second
Take wired gigabit ethernet, roughly 0.116 GiB/s. The conversion is a single multiplication — 0.116 × 1.07374e+06 — giving 124,554 kB/s. Because the relationship is proportional, doubling the input doubles the answer to 249,108 kB/s.
SD video stream: 0.000349 GiB/s in kilobytes per second
At 0.000349 GiB/s (sd video stream), the same quantity in kilobytes per second is 0.000349 × 1.07374e+06 = 374.736 kB/s. One gibibyte per second is 1.07374e+06 kilobytes per second, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many kilobytes per second are in one gibibyte per second?
Exactly 1,073,741.824. 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 kilobytes per second?
kilobytes per second = gibibytes per second × 1,073,741.824. Reversed, gibibytes per second = kilobytes per second ÷ 1,073,741.824, which is the same as multiplying by 9.31322574615e-07.
Which is the bigger unit, the gibibyte per second or the kilobyte per second?
The gibibyte per second. One gibibyte per second equals 1.07374e+06 kilobytes 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 kilobyte per second?
Kilobytes per second is what a download dialog shows on a slow connection: 1 kB/s is 8 kbit/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 kB/s in my head?
Plenty of people do this in their head: multiply by 1100000.000000 instead of using the exact factor 1,073,741.824. At 100 that shortcut gives 110000000.000000 kilobytes per second, off by 2625817.600000 kilobytes per second or about 2.45%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
