khz to hertz | Exact Decimal + Formula
1 Kilohertz = 1000 Hertz
One kilohertz equals exactly a thousand hertz. Real-world use: am radio bands and ultrasonic applications. This page expresses those values in hertz, which is used for audio frequencies, processor clock rates, and AC power mains (50/60 hz). Type a value above for an instant answer; the exact formula and the reference table are below.
About Kilohertz and Hertz
Kilohertz (kHz)
A kilohertz is 1,000 hertz.
Where it's used: AM radio bands and ultrasonic applications.
Hertz (Hz)
The hertz measures cycles per second.
Where it's used: Audio frequencies, processor clock rates, and AC power mains (50/60 Hz).

kHz to Hz Formula and Examples
Direct Formula
Hz = kHz × 1000 Inverse Formula
kHz = Hz × 0.001 Mental Math Shortcut
Multiply the value by roughly 1000 to calculate the equivalent amount in your head.
Common Kilohertz to Hertz Calculations
- 5 kHz = 5000 Hz
- 10 kHz = 10000 Hz
- 50 kHz = 50000 Hz
- 100 kHz = 100000 Hz
- 500 kHz = 500000 Hz
Precision & Practical Use
For example, 10 kHz = 10000 Hz — roughly multiple unit increments.
Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Kilohertz to Hertz
How many hertzes are in one kilohertz?
One Kilohertz (kHz) equals 1000 Hertz (Hz). To convert kilohertzes to hertzes, multiply the kilohertz value by 1000.
How do I convert Kilohertz to Hertz?
Multiply your kilohertz value by 1000 to get the result in Hertz: Hz = kHz × 1000. For example, 5 kHz = 5000 Hz.
What is the formula for converting kHz to Hz?
The conversion formula is Hz = kHz × 1000. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for kHz to Hz?
Multiply the value by roughly 1000 to calculate the equivalent amount in your head.
