The conversion of 5 hz to radians per second results in approximately 31.416 rad.
Since 1 Hz equals 2π radians per second, multiplying 5 Hz by 2π gives the value in radians per second. This means that a frequency of 5 cycles per second corresponds to about 31.416 radians per second, because each cycle is 2π radians.
Introduction
Converting 5 Hz to radians involves multiplying by 2π because frequency in hertz measures cycles per second, and radians measure angular displacement. The formula connects the two by expressing how many radians occur in one cycle. For 5 Hz, the calculation becomes 5 * 2π, resulting in 31.416 rad.

Conversion Formula
The formula to convert hz to rad is: radians = hz * 2π. Because 1 cycle equals 2π radians, multiplying the frequency in Hz by 2π gives the total radians per second. For example, 5 Hz times 2π equals 31.416 radians. This conversion works because it relates cycles to angular displacement.
Conversion Example
- Convert 10 Hz to rad:
- Multiply 10 by 2π.
- 10 * 2π = 20π ≈ 62.832 rad.
- Result: 62.832 radians.
- Convert 2.5 Hz to rad:
- Multiply 2.5 by 2π.
- 2.5 * 2π = 5π ≈ 15.708 rad.
- Result: 15.708 radians.
- Convert 0.1 Hz to rad:
- Multiply 0.1 by 2π.
- 0.1 * 2π = 0.2π ≈ 0.628 rad.
- Result: 0.628 radians.
- Convert 15 Hz to rad:
- Multiply 15 by 2π.
- 15 * 2π = 30π ≈ 94.248 rad.
- Result: 94.248 radians.
- Convert 0.5 Hz to rad:
- Multiply 0.5 by 2π.
- 0.5 * 2π = π ≈ 3.142 rad.
- Result: 3.142 radians.

Conversion Definitions
Hz
Hertz (Hz) is a unit measuring how many complete cycles or oscillations happen per second in a wave or signal. It quantifies frequency, indicating the number of repetitions or oscillations in one second, used in physics and engineering to describe wave phenomena.
Rad
Radian (rad) is a measure of angular displacement, representing the angle created when the arc length equals the radius. One radian equals about 57.2958 degrees, and it provides a natural way to measure angles in mathematical and physical calculations involving circles.
Conversion FAQs
Why does multiplying by 2π convert Hz to radians?
Because a full cycle in Hz corresponds to 2π radians, multiplying the frequency by 2π transforms the number of cycles per second into total radians per second, reflecting how many radians are swept in that period of oscillation.
Can I convert Hz to radians without knowing the formula?
Directly, no. The conversion relies on the fundamental relationship that one cycle equals 2π radians. Without this, you would not be able to accurately convert frequency units to angular displacement, so knowing the formula is essential.
Is the conversion different for angular velocity and frequency?
Yes, angular velocity (rad/sec) directly relates to frequency (Hz) via the multiplication by 2π, but they measure different aspects—angular velocity involves rotation rate, while frequency measures cycles per second. The conversion bridges these two concepts.
