What is the difference between Hertz (Hz) and RPM?

Hertz (Hz) measures cycles per second, while RPM measures rotations per minute. Since a rotation is a type of cycle, they are directly convertible. 1 Hz is equal to 60 RPM.

What is Radian per second (rad/s)?

Radian per second is a unit of angular velocity. It describes the rate at which an object rotates. One full rotation is equal to 2π radians. Radian per second is the standard unit of angular frequency in the SI system.

What is the relationship between Hz and Radian per second?

Hertz (cycles per second) and Radian per second are both units of frequency. Since one cycle is 2π radians, 1 Hz is equal to 2π rad/s (approximately 6.283 rad/s). This conversion is fundamental in physics and engineering.

Where are these frequency measurements used?

Hz, kHz, MHz, and GHz are used for electronics, radio waves, and computer speeds. RPM is used for mechanical systems like engines and hard drives. Rad/s and Deg/s are used extensively in engineering, robotics, and physics to describe rotational motion.

About the Frequency Converter

Frequency is a measure of how often a repeating event occurs over time. While this often relates to waves and oscillations, it’s also fundamental to describing rotational motion. The Frequency Converter from TechnoCodex is a comprehensive tool designed to bridge these applications, allowing you to instantly convert between standard frequency units (Hz, kHz, MHz, GHz) and units of angular velocity like RPM, Degree per second, and Radian per second.

This expanded frequency conversion calculator is an indispensable resource for a diverse range of fields. It’s built for engineers working with electric motors, mechanics analyzing engine speeds, physicists studying circular motion, and students learning the connections between different systems of measurement. The ability to quickly convert RPM to Hz or rad/s to RPM is crucial for accurate calculations and a unified understanding of rotational and periodic phenomena.

How to Use the Frequency Converter

Our tool is designed for an efficient and user-friendly experience. Get your conversion in three simple steps:

Enter Your Value: Type the frequency or rotational speed you wish to convert into the “Amount” field.
Select Your Units: Choose your starting unit from the “From” dropdown menu (e.g., Rotation per minute) and your target unit from the “To” dropdown menu (e.g., Hertz).
Click “Convert”: The accurate converted value will immediately appear in the result box.

Understanding the Key Units of Frequency

Our converter now handles both linear and angular frequency:

Hertz (Hz, kHz, MHz, GHz): The Hertz is the SI unit of frequency, equal to one cycle per second. It and its multiples are used for sound waves, radio waves, and computer clock speeds.
Rotation per minute (rpm): A widely used unit for measuring the speed of mechanical components. It’s the standard for car engines, computer fans, hard drives, and industrial machinery. A RPM to Hz conversion is common for analyzing the frequency of vibrations produced by rotating parts.
Degree per second (deg/s): A unit of angular velocity that measures how many degrees an object rotates in one second. It’s often used in robotics, servo control, and scientific instruments to describe precise rotational movements.
Radian per second (rad/s): The Radian per second is the standard SI unit for angular velocity. It is the most common unit used in physics and engineering formulas related to rotational dynamics. One full rotation is 2π radians. Converting rad/s to Hz is a fundamental step in many engineering calculations.

Common Use Cases and Applications

Automotive and Mechanical: Convert engine speed from RPM to rad/s for engineering calculations or to Hz to analyze vibrations.
Robotics and Control Systems: Convert motor specifications between RPM and rad/s to design and program robotic arms and servo systems.
Physics and Engineering: An essential tool for students and professionals to convert between the units used in theoretical formulas (rad/s) and practical applications (RPM).
Computer Technology: Understand the rotational speed of hard drives (in RPM) and its relation to data access frequency.

By unifying linear and angular frequency in one simple tool, the TechnoCodex Frequency Converter is the go-to resource for anyone working with periodic or rotational systems.
