What Is Hertz (Hz)?
Hertz, abbreviated as Hz, is the unit used to measure frequency. One Hertz means that one complete cycle occurs every second.
Definition:
1 Hz = 1 cycle per second
Examples include:
- A pendulum swinging once every second operates at 1 Hz.
- Household electrical power commonly operates at 50 Hz or 60 Hz.
- Audio frequencies range from approximately 20 Hz to 20,000 Hz.
- Computer processors often operate in GHz (gigahertz), which are billions of Hz.
Frequency measurement is fundamental in many scientific and engineering fields because it describes how often a repeating event occurs.

Hz Conversion Formulas
The Hz Calculator uses standard mathematical formulas for each conversion type.
1. Convert Hz to Period (Seconds)
The period is the time required for one complete cycle.
Formula:
Period (T) = 1 ÷ Frequency (Hz)
Example:
Frequency = 50 Hz
Period = 1 ÷ 50
Period = 0.02 seconds
2. Convert Hz to RPM
RPM stands for Revolutions Per Minute and is commonly used in motors and rotating machinery.
Formula:
RPM = Hz × 60
Example:
Frequency = 20 Hz
RPM = 20 × 60
RPM = 1200 RPM
3. Convert Hz to Kilohertz (kHz)
One kilohertz equals one thousand hertz.
Formula:
kHz = Hz ÷ 1000
Example:
Frequency = 5000 Hz
kHz = 5000 ÷ 1000
kHz = 5 kHz
4. Convert Hz to Megahertz (MHz)
One megahertz equals one million hertz.
Formula:
MHz = Hz ÷ 1,000,000
Example:
Frequency = 5,000,000 Hz
MHz = 5,000,000 ÷ 1,000,000
MHz = 5 MHz
