Conversion Result: 5 Hz equals approximately 31.4160 radians
Converting 5 Hz to radians involves multiplying the frequency in hertz by 2π because 1 Hz corresponds to 2π radians per second. This conversion is crucial in fields like signal processing, where understanding angular measures in radians is essential for analyzing waveforms and oscillations.
Introduction
Frequency in hertz measures how many cycles occur per second. Radians, on the other hand, measure angles, with 2π radians representing a full circle. To convert from hz to rad, you multiply the frequency by 2π, translating cycles into angular displacement, which is often needed in physics and engineering tasks.

Conversion Formula
The formula to convert hz to radians is: radians = hz × 2π. It works because one cycle equals 2π radians, so multiplying the frequency in cycles per second by 2π gives the angular displacement in radians per second. For example, 5 Hz times 2π equals 31.416 radians, since 5 × 2π = 5 × 6.2832 ≈ 31.416.
Conversion Example
- Convert 10 Hz:
- Multiply 10 by 2π: 10 × 6.2832 = 62.832 radians.
- Result is approximately 62.832 radians.
- Convert 0.5 Hz:
- Multiply 0.5 by 2π: 0.5 × 6.2832 = 3.1416 radians.
- Result is approximately 3.1416 radians.
- Convert 20 Hz:
- Multiply 20 by 2π: 20 × 6.2832 = 125.664 radians.
- Result is approximately 125.664 radians.

Conversion Definitions
Hz
Hz, or hertz, is a unit of frequency measuring how many cycles or oscillations occur in one second. It is used in physics, electronics, and audio to express how often a repeating event happens per second.
Rad
Rad, or radians, is a unit of angular measure representing the angle where the arc length equals the radius. One full circle equals 2π radians, making it fundamental in trigonometry, physics, and engineering for describing rotations and wave phases.
Conversion FAQs
Why does multiplying by 2π convert Hz to radians?
Because 1 Hz equals one cycle per second, and each cycle corresponds to 2π radians, multiplying Hz by 2π converts cycles into their equivalent angular measure in radians, which is often used in wave and oscillation calculations.
Can I use this conversion for angular velocity?
Yes, when dealing with angular velocity, converting from Hz to radians per second gives the rate of change of angle in radians per second, essential in rotational motion analysis and physics applications.
What if I want to convert radians back to Hz?
To convert radians back to Hz, divide the radian value by 2π. Because radians = hz × 2π, rearranging gives hz = radians / 2π, allowing you to switch between angular and frequency measures.
Is this conversion valid for all frequencies?
Yes, the conversion applies across all frequencies because it is based on fundamental relationships between cycles and angles, making it valid for any oscillating or rotating system.
