1 Hz equals approximately 6.2832 radians
Converting 1 hertz (Hz) to radians results in about 6.2832 radians. This is because 1 Hz, which measures cycles per second, corresponds to one complete cycle, and each cycle equals 2π radians.
Since 1 Hz is one cycle per second, and one cycle is 2π radians, multiplying 1 by 2π gives the radians per second. Therefore, 1 Hz equals 2π radians, approximately 6.2832, which links frequency in hertz to angular displacement in radians.

Conversion Formula
The formula to convert Hz to radians is: radians = Hz × 2π. This works because one cycle, which corresponds to 1 Hz, equals 2π radians. So, multiplying the frequency in Hz by 2π converts it into an angular measure in radians per second.
For example, if you have 2 Hz, multiply 2 by 2π (which is approximately 6.2832), giving 12.5664 radians. This calculation shows how many radians are completed per second at that frequency, since each cycle equals 2π radians.
Conversion Example
- Example 1: Convert 0.5 Hz to radians.
- Multiply 0.5 by 2π.
- 0.5 × 6.2832 ≈ 3.1416 radians.
- This means half a cycle per second equals approximately 3.1416 radians.
- Example 2: Convert 5 Hz to radians.
- Multiply 5 by 2π.
- 5 × 6.2832 ≈ 31.416 radians.
- This indicates 5 cycles per second is about 31.416 radians.
- Example 3: Convert 10 Hz to radians.
- Multiply 10 by 2π.
- 10 × 6.2832 ≈ 62.832 radians.
- Ten cycles per second equals roughly 62.832 radians.

Conversion Definitions
Hz
Hz, or hertz, measures how many complete cycles or oscillations occur in one second. It is a unit of frequency used in wave, signal, and oscillation analysis to describe how often a repeating event happens per second.
Rad
Rad, or radians, is a unit of angular measurement representing the ratio of the length of an arc to its radius. It describes the angle in a circle, where one full circle equals 2π radians, used for calculations in rotation and oscillatory systems.
Conversion FAQs
How do I interpret 1 Hz in terms of radians?
1 Hz equals 2π radians because each cycle in frequency corresponds to a full rotation of 2π radians, representing one complete oscillation. So, 1 cycle per second is equivalent to 6.2832 radians per second.
Can I convert any frequency in Hz to radians using the same formula?
Yes, the formula radians = Hz × 2π applies for all frequencies, converting cycles per second into angular displacement in radians per second, which is useful for analyzing wave angular velocity.
What does the radians value tell me about the wave?
The radians value indicates how many radians the wave covers per second. Higher radians mean faster angular change, signifying a higher frequency or quicker oscillation in the wave cycle.
Is the conversion from Hz to radians linear?
Yes, the relationship is linear. Doubling Hz doubles radians, tripling Hz triples radians, as the formula involves a simple multiplication by 2π, maintaining a direct proportionality.
