Frequency Converter
Free Frequency Converter, Convert Hz, kHz, MHz, GHz, THz & RPM Instantly
Convert frequency between any units instantly with OmniConverter's free online frequency converter. 1 kilohertz equals 1,000 hertz, 1 megahertz equals 1,000 kHz, and 1 gigahertz equals 1,000 MHz. Supports Hz, kHz, MHz, GHz, THz, RPM, and radians per second. Whether you're working with electronics, audio engineering, or CPU speeds, our converter delivers precise, instant results.
How It Works
Convert in three simple steps.
Enter the Frequency Value
Type your frequency measurement into the Input Value field. For example, enter 2400 to convert 2400 MHz (typical for Wi-Fi) or 60 to convert 60 Hz (AC power frequency).
Choose Source and Target Frequency Units
Select your input unit on the left (e.g., hertz, kilohertz, megahertz, gigahertz, RPM) and your desired output unit on the right dropdown.
View Your Converted Frequency Result
The converted frequency displays immediately. Useful for electronics, audio engineering, radio communications, CPU clock speed comparisons, and motor RPM to Hz calculations.

Quick answers to common conversion questions
How do I convert hertz to kilohertz?+
Divide hertz by 1,000 to get kilohertz.
What is RPM?+
RPM stands for revolutions per minute, a common way to express rotational speed.
How do I convert MHz to Hz?+
Multiply megahertz by 1,000,000.
What is a gigahertz used for?+
GHz is commonly used for processor clock speed and radio frequency ranges.
Can I convert rad/s to RPM?+
Yes, use the appropriate constant to convert angular speed into revolutions per minute.
Why are frequency units important?+
They describe how often a signal repeats, which matters in electronics and communications.
What is the difference between Hz and kHz?+
kHz is 1,000 times larger than Hz.
How do I convert THz to GHz?+
Divide terahertz by 1,000 to get gigahertz.
Are cycles per second and hertz the same?+
Yes, hertz is the SI term for cycles per second.
What is a common unit for radio signals?+
Megahertz and gigahertz are widely used in wireless communications.
