Formula: f₂ = f₁ × (conversion factor)
What is Frequency?
Frequency is how many times something happens in one second. We measure frequency in hertz (Hz). One hertz means one cycle per second. Frequency is very important in many areas of life.
Sound waves have frequency. Radio waves have frequency. Light waves have frequency too. Higher frequency means more cycles per second. Lower frequency means fewer cycles per second.
Our frequency converter helps you change between different frequency units easily. You can convert Hz to kHz, MHz to GHz, and many other frequency units quickly.
Common Frequency Units
Hertz (Hz)
Basic unit of frequency. One cycle per second.
Kilohertz (kHz)
1,000 Hz. Used for audio frequencies and AM radio.
Megahertz (MHz)
1,000,000 Hz. Used for FM radio and TV signals.
Gigahertz (GHz)
1,000,000,000 Hz. Used for computer processors and WiFi.
Terahertz (THz)
1,000,000,000,000 Hz. Used for infrared light.
Cycles per Second
Same as Hz. Old way to measure frequency.

Frequency Conversion Practice Problems
Problem 1: Audio Frequency
Convert 440 Hz (musical note A) to kHz
Solution: 440 Hz ÷ 1000 = 0.44 kHz
Problem 2: Radio Frequency
Convert 100.5 MHz (FM radio) to Hz
Solution: 100.5 MHz × 1,000,000 = 100,500,000 Hz
Problem 3: WiFi Frequency
Convert 2.4 GHz (WiFi) to MHz
Solution: 2.4 GHz × 1000 = 2400 MHz
Problem 4: Microwave Frequency
Convert 2.45 GHz (microwave oven) to Hz
Solution: 2.45 GHz × 1,000,000,000 = 2,450,000,000 Hz
Problem 5: Low Frequency
Convert 50 Hz (power line frequency) to kHz
Solution: 50 Hz ÷ 1000 = 0.05 kHz
Problem 6: High Frequency
Convert 5 GHz (WiFi 5GHz band) to MHz
Solution: 5 GHz × 1000 = 5000 MHz

Frequently Asked Questions
What is frequency and how is it measured?
Frequency is the number of cycles or waves that occur in one second. It is measured in hertz (Hz). One hertz equals one cycle per second.
How do I convert Hz to kHz?
To convert hertz to kilohertz, divide the Hz value by 1,000. For example: 5,000 Hz ÷ 1,000 = 5 kHz.
What is the difference between MHz and GHz?
MHz (megahertz) is 1 million Hz, while GHz (gigahertz) is 1 billion Hz. GHz is 1,000 times larger than MHz.
Why do we need different frequency units?
Different frequency units make it easier to work with very large or very small numbers. Instead of writing 2,400,000,000 Hz, we can simply write 2.4 GHz.
Is this frequency converter accurate?
Yes, our frequency converter uses precise mathematical formulas to ensure accurate conversions between all supported frequency units.
