To convert terabits per second to gibibytes per second, multiply by 116.4153218. 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.
Terabits per second describes backbone and submarine cable capacity rather than anything you can buy for a house. 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.
The formula
terabits per second- The amount you are converting, in terabits per second

Worked examples
Wi-Fi 6 link rate: 0.0012 Tbit/s in gibibytes per second
Wi-Fi 6 link rate comes to about 0.0012 Tbit/s. Multiplying by the factor: 0.0012 × 116.415 = 0.139698 GiB/s. Dividing the answer back by 116.415 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
Wired gigabit Ethernet: 0.001 Tbit/s in gibibytes per second
Wired gigabit Ethernet comes to about 0.001 Tbit/s. Multiplying by the factor: 0.001 × 116.415 = 0.116415 GiB/s. Dividing the answer back by 116.415 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
How to read your score
Frequently asked questions
How many gibibytes per second are in one terabit per second?
Exactly 116.415321827. 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 terabits per second to gibibytes per second?
gibibytes per second = terabits per second × 116.415321827. Reversed, terabits per second = gibibytes per second ÷ 116.415321827, which is the same as multiplying by 0.008589934592.
Which is the bigger unit, the terabit per second or the gibibyte per second?
The terabit per second. One terabit per second equals 116.415 gibibytes 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 terabit per second?
Terabits per second describes backbone and submarine cable capacity rather than anything you can buy for a house.
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 Tbit/s to GiB/s in my head?
Plenty of people do this in their head: multiply by 120 instead of using the exact factor 116.4153218. At 100 that shortcut gives 12,000 gibibytes per second, off by 358.5 gibibytes per second or about 3.08%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
