Gigabytes to Kilobits formula
To convert gigabytes to kilobits, multiply by 8000000.
Kb = GB × 8000000
Why this factor: the gigabyte and the kilobit are both defined against the byte, so dividing one definition by the other gives 8000000 directly. Both definitions are set out in full below.
To go the other way, divide by 8000000 — or use the Kilobits to Gigabytes converter, which is the same calculation reversed.
Worked example
Take 4 GB and multiply by the factor 8000000: the result is 32000000 Kb.
4 GB × 8000000 = 32000000 Kb
The converter above does this for any value you type, in either direction.
What is a gigabyte?
A gigabyte is one billion bytes — the everyday unit of storage and memory capacity.
Definition: Exactly 1,000,000,000 bytes under SI prefixes. The binary gibibyte (GiB) is 1,073,741,824 bytes.
Where it is used: Phone and laptop storage, RAM capacity, video file sizes, and cloud storage plans.
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.
Gigabytes vs Kilobits
The gigabyte and the kilobit 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.
