Instant Frequency Unit Conversion Tool

Frequency, the measure of cycles per second, is a cornerstone of physics, engineering, telecommunications, and mechanical systems. Whether you're a radio hobbyist tuning into a broadcast in megahertz (MHz), an engineer analyzing motor speed in revolutions per minute (RPM), or a scientist studying wave phenomena in hertz (Hz), you often need to switch between units. Our free Frequency Converter makes these calculations effortless and accurate.

This tool seamlessly converts between the most common frequency units, including hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), revolutions per minute (RPM), and radians per second (rad/s). Eliminate manual errors and complex formulas from your workflow with our reliable, user-friendly converter.

Frequently Asked Questions About Frequency Conversion

What does a frequency converter do?

A physical frequency converter is an electronic device that changes the frequency of an AC power source to another frequency. For example, it can convert 60Hz power to 50Hz power to run equipment from a different region. This online tool, however, is a unit converter; it mathematically converts the measurement of frequency from one unit (like MHz) to another (like kHz).

How to convert 60Hz to 50Hz?

Converting 60Hz to 50Hz requires a physical device called a static frequency converter or a motor-generator set. It's not a simple calculation. The modern electronic method involves a two-step process: first, the incoming AC power (60Hz) is converted to DC power (rectification); second, the DC power is converted back into clean, new AC power at the desired frequency (50Hz) using an inverter.

What is the basic principle of frequency conversion?

The basic principle of a modern electronic frequency converter is an AC-to-DC-to-AC conversion. The first stage (rectifier) converts the source AC voltage into a stable DC voltage. The second stage (inverter), using high-speed switches like IGBTs, chops up the DC voltage and reassembles it into a new AC sine wave at the required output frequency and voltage.

What is the difference between a frequency converter and an inverter?

An inverter is a core component of a frequency converter. An inverter's job is to convert DC power to AC power. A frequency converter is a complete system that typically converts AC power of one frequency to AC power of another frequency. To do this, it uses a rectifier (AC to DC) followed by an inverter (DC to AC). So, an inverter is just half of the process.

Why are frequency converters necessary?

Frequency converters are necessary for several key reasons: 1. International Power Compatibility: To run equipment designed for 50Hz in a 60Hz country, or vice versa. 2. Motor Speed Control: Variable Frequency Drives (VFDs) are frequency converters that adjust the frequency to precisely control the speed of AC motors, saving energy. 3. Specialized Applications: For testing or operating equipment in aviation and marine industries that use different power standards (e.g., 400Hz).
