Frequency Converter

Convert between hertz, kilohertz, RPM, and other frequency units.

Understanding the Converter

Frequency is the number of occurrences of a repeating event per unit of time. It's a fundamental concept in physics and engineering, used to describe waves, computer processors, and rotational speed.

All conversions use Hertz (Hz), the SI unit of frequency, as a base reference to ensure accuracy.

Formula Used

Standardized Conversion Process

To ensure accuracy, all conversions use Hertz (Hz) as a common base unit.

  1. Convert to Hertz: The input value is converted to Hertz by multiplying it by its conversion factor.
  2. Convert to Target Unit: The Hertz value is then converted to the desired final unit by dividing it by the target unit's conversion factor.

A Guide to Units of Frequency

From sound waves to computer clocks, frequency measures how often something happens.

Common Frequency Units

UnitDefinition & Context
Hertz (Hz)One cycle per second. The SI unit for frequency. Used for sound waves, light waves, and AC electricity.
Kilohertz (kHz)1,000 Hertz. Used for AM radio broadcast frequencies.
Megahertz (MHz)1 million Hertz. Used for FM radio and older computer processor speeds.
Gigahertz (GHz)1 billion Hertz. Standard for modern computer processors, Wi-Fi, and mobile networks.
Revolutions per minute (rpm)A unit of rotational speed. One rpm is one revolution in a minute. Used for car engines, hard drives, and record players.

Frequently Asked Questions

What is the relationship between frequency and wavelength?

They are inversely proportional. For electromagnetic waves (like light and radio), the formula is: Wavelength = Speed of Light / Frequency. Higher frequency means shorter wavelength, and vice versa.

What does a computer's GHz rating mean?

The Gigahertz (GHz) rating of a CPU is its clock speed, indicating how many processing cycles it can execute per second. A 3 GHz CPU performs 3 billion cycles per second. While a useful metric, it's not the only factor determining a processor's overall performance.

How is RPM converted to Hertz?

Since RPM is "revolutions per minute" and Hertz is "cycles per second," you convert by dividing by 60. For example, an engine running at 6000 RPM is completing 100 revolutions per second, so its frequency is 100 Hz.

What frequency is human hearing?

The typical range for human hearing is from about 20 Hz to 20,000 Hz (20 kHz). Frequencies below this range are called infrasound, and those above are ultrasound.

Summary

The Frequency Converter is a key tool for engineers, physicists, and computer technicians. It provides fast and accurate conversions between different units of frequency, from rotational speed to processor clock cycles.
