Kilobits to Gigabits formula
To convert kilobits to gigabits, multiply by 1e-06.
Gb = Kb × 1e-06
Why this factor: the kilobit and the gigabit are both defined against the byte, so dividing one definition by the other gives 1e-06 directly. Both definitions are set out in full below.
To go the other way, divide by 1e-06 — or use the Gigabits to Kilobits converter, which is the same calculation reversed.
Worked example
Given 4 Kb, multiplying by 1e-06 yields 4e-06 Gb.
4 Kb × 1e-06 = 4e-06 Gb
The converter above does this for any value you type, in either direction.
What is a kilobit?
A kilobit is 1,000 bits, used almost exclusively for data rates.
Definition: Exactly 1,000 bits, so exactly 125 bytes.
Where it is used: Audio and video bitrates, and legacy connection speeds.
What is a gigabit?
A gigabit is one billion bits, the unit of modern high-speed networking.
Definition: Exactly 1,000,000,000 bits, so exactly 125,000,000 bytes.
Where it is used: Gigabit Ethernet, fiber broadband tiers, and data-centre interconnects.
Kilobits vs Gigabits
The kilobit and the gigabit belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
