What Is Frequency?

Frequency represents how often a repeating event occurs per unit of time. In physics and engineering, it's most commonly expressed in Hertz (Hz), where 1 Hz equals one cycle per second.

For example, alternating current (AC) power in most countries operates at 50 or 60 Hz. Audio signals, radio waves, and light waves also use frequency to describe their properties.

Unit Descriptions

• Hertz (Hz): One cycle per second.
• Kilohertz (kHz): 1,000 Hz.
• Megahertz (MHz): 1,000,000 Hz.
• Gigahertz (GHz): 1,000,000,000 Hz.
• Terahertz (THz): 1,000,000,000,000 Hz.
• Rotations per Minute (rpm): Number of full turns completed in one minute.
• Degree per second (deg/s): Angular velocity measured in degrees.
• Radian per second (rad/s): Standard angular unit in SI, where 1 full circle = 2π radians.

Common Use Cases

• Electrical and electronic signal analysis

FAQs

What is the difference between Hz and rpm?

Hz measures the number of complete cycles per second, while rpm (rotations per minute) measures complete cycles per minute. To convert rpm to Hz, divide by 60.

Is frequency the same as speed?

Not exactly. Frequency measures cycles per second, while speed refers to distance covered per unit of time. They’re related but not identical.

Can this converter handle angular velocity?

Yes. It supports degrees per second (deg/s) and radians per second (rad/s), useful for mechanical and physics applications.
