Convert Gigabits to Kilobits (Gbit to kbit)
1 gigabit (Gbit) = 1000000 kilobits (kbit). 1 kbit = 0.000001 Gbit. Example: 15 Gbit = 15 × 1000000 = 15000000 kbit.

How to Convert Gigabit to Kilobit
- 1 Gbit = 1000000 kbit
- 1 kbit = 0.000001 Gbit
- Example: convert 15 Gbit to kbit: 15 Gbit = 15 × 1000000 kbit = 15000000 kbit
Formula
kbit = Gbit × 1000000
Derivation from SI units:
- 1 Gbit = 10⁹ bits.
- 1 kbit = 1000 bits (SI prefix kilo = 10³).
- 1 Gbit = 1000000000 bit ÷ 1000 bit per kbit = 1000000 kbit
Both units are defined exactly, so the factor is exact. Gigabit definition: gigabit; Kilobit definition: kilobit.
Worked examples
- A reading of 16 Gbit converts to 16000000 kbit.
16 Gbit × 1000000 = 16000000 kbit - A value of 128 Gbit is 128000000 kbit.
128 Gbit × 1000000 = 128000000 kbit
