Frequency Converter
Convert between Hz, kHz, MHz, GHz, and RPM.
📡 CPU clocks in GHz, audio in Hz-kHz, rotation in RPM.
What Is This Tool?
This tool converts between frequency units: hertz, kilohertz, megahertz, gigahertz, and rotations per minute (RPM). Frequency measures how often something repeats per second.
Key Conversions
- 1 kilohertz (kHz) = 1,000 Hz
- 1 megahertz (MHz) = 1,000,000 Hz
- 1 gigahertz (GHz) = 1,000 MHz = 1 billion Hz
- 1 RPM = 1/60 Hz ≈ 0.0167 Hz
Frequencies You Encounter
- Heart rate: 60-100 beats/min = 1-1.7 Hz
- Audio (human hearing): 20 Hz - 20 kHz
- AM radio: 530-1710 kHz
- FM radio: 88-108 MHz
- WiFi: 2.4 GHz or 5 GHz
- CPU clock speed: 2-5 GHz in modern computers
Why Frequencies Matter
In electronics and communications, the frequency band determines what a signal can do. Lower frequencies (AM radio) travel farther but carry less data; higher frequencies (WiFi, 5G) carry more data but over shorter distances. This trade-off shapes the entire design of wireless systems.
Frequently Asked Questions
How do I convert RPM to Hz?
Divide RPM by 60. A motor spinning at 3,600 RPM runs at 60 Hz. This is why AC power in the US is 60 Hz — generators spin at 3,600 RPM.
About the Frequency Converter
The Frequency Converter converts frequency converterfrom one unit to another using the exact internationally defined conversion factors. Type a value, choose your source and target units, and the converted result is shown instantly — no waiting, no page reload.
Manual conversion is error-prone because it means memorizing ratios (how many feet in a meter, how many pints in a liter). This tool removes that friction: the conversion factor is built in, and the math is done to full precision with no rounding until the final displayed number.
How to Use This Tool
- Enter the value you want to convert in the input field.
- Select the unit you are converting from.
- Select the unit you want to convert to.
- The converted value appears instantly. Adjust either unit to compare across the board.
- Copy the result if you need it elsewhere. Your input is never sent anywhere.
Why Use an Online Converter?
Browser-based tools like this one have a few real advantages over installed software or manual methods:
- No installation. It opens instantly in any browser, on any operating system.
