How to use
- Enter a value in the Kilohertz field.
- The Gigahertz figure appears immediately — no button to press.
- Typing in the Gigahertz field converts back to Kilohertz the same way.
- Use the reference table for the values that come up most often.
Kilohertz to Gigahertz formula
To convert kilohertz to gigahertz, multiply by 1e-06.
GHz = kHz × 1e-06
Why this factor: the kilohertz and the gigahertz are both defined against the hertz, 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 Gigahertz to Kilohertz converter, which is the same calculation reversed.
Worked example
Given 60 kHz, multiplying by 1e-06 yields 6e-05 GHz.
60 kHz × 1e-06 = 6e-05 GHz
The converter above does this for any value you type, in either direction.
What is a kilohertz?
A kilohertz is 1,000 cycles per second.
Definition: Exactly 1,000 hertz.
Where it is used: AM radio frequencies, audio sample rates (44.1 kHz for CD audio), and ultrasonic ranges.
What is a gigahertz?
A gigahertz is one billion cycles per second — the scale of modern processors and wireless.
Definition: Exactly 1×10⁹ hertz.
Where it is used: CPU clock speeds, Wi-Fi bands (2.4 and 5 GHz), mobile networks, and radar.
Kilohertz vs Gigahertz
The kilohertz and the gigahertz 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.
