Kilohertz (kHz) to Hertz (Hz) Converter
Enter a value to instantly convert between frequency units.
1 Kilohertz = 1000 Hertz
Key Formulas
Hertz → Kilohertz
kHz = Hz × 0.001Kilohertz → Hertz
Hz = kHz × 1000Megahertz → Gigahertz
GHz = MHz × 0.001Gigahertz → Megahertz
MHz = GHz × 1000Formula
Hz = kHz × 1000When you're reading audio or radio specifications in kilohertz but need to work with equipment or formulas that expect hertz, you need this conversion. Knowing the exact frequency in Hz helps you understand oscillation rates, AC power characteristics, and audio sampling requirements.
Frequently Asked Questions
Real-World Examples
One kilohertz. 1 kHz = 1,000 Hz (cycles per second). Used as a baseline for frequency ranges.
1 kHz = 1000 Hz
Upper human hearing limit. 20 kHz = 20,000 Hz. Audio equipment targeting humans often specifies 20 Hz - 20 kHz range.
20 kHz = 20000 Hz
High-frequency ultrasonic. 100 kHz = 100,000 Hz. Used in ultrasound and medical imaging.
100 kHz = 100000 Hz
Bluetooth frequency. 2.4 GHz = 2,400 MHz = 2,400,000 kHz. WiFi and Bluetooth operate here.
2.4 kHz = 2400 Hz
