Kilobits to Gigabytes formula
Converting kilobits to gigabytes is a single multiplication by 1.25e-07.
GB = Kb × 1.25e-07
Why this factor: the kilobit and the gigabyte are both defined against the byte, so dividing one definition by the other gives 1.25e-07 directly. Both definitions are set out in full below.
To go the other way, divide by 1.25e-07 — or use the Gigabytes to Kilobits converter, which is the same calculation reversed.
Worked example
Start with 64 Kb. Multiply by 1.25e-07 to get 8e-06 GB.
64 Kb × 1.25e-07 = 8e-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.
