2 Hz equals approximately 12.5664 radians
Converting 2 Hz to radians results in about 12.5664 radians. This is because Hz measures cycles per second, while radians measure angles; multiplying the frequency by 2π converts cycles into radians.
Introduction
Frequency in hertz (Hz) refers to how many oscillations or cycles happen in one second. Radians measure the angle traveled in a circle, with one full circle being 2π radians. To convert from Hz to radians per second, you multiply the frequency by 2π.

Conversion Formula
The conversion from Hz to radians involves multiplying the frequency by 2π. Because 1 cycle equals 2π radians, this formula converts the number of cycles per second into radians per second. For example, if frequency is 2 Hz, then:
- Radians = 2 Hz × 2π = 2 × 6.2832 = 12.5664 radians
This method works because it directly relates the number of cycles to the angle measure in radians, aligning with how circular motion is measured.
Conversion Example
- Convert 5 Hz to radians:
- Multiply 5 by 2π
- 5 × 6.2832 = 31.416 rad
- This means 5 Hz equals about 31.416 radians per second.
- Convert 0.5 Hz:
- 0.5 × 2π
- 0.5 × 6.2832 = 3.1416 rad
- So, 0.5 Hz is approximately 3.1416 radians per second.
- Convert 10 Hz:
- 10 × 2π
- 10 × 6.2832 = 62.832 rad
- Thus, 10 Hz equals about 62.832 radians per second.

Conversion Definitions
Hz
Hertz (Hz) is a measure of frequency indicating how many complete cycles or oscillations occur in one second. It is used to describe wave vibrations, sound, and electromagnetic signals, giving a count of cycles per second.
Rad
Radians (rad) are units of angular measurement, representing the angle subtended at the center of a circle by an arc equal in length to the radius. One full circle is 2π radians, linking linear distance to angle in circular motion.
Conversion FAQs
How does frequency in Hz relate to radians in circular motion?
Frequency in Hz measures how many cycles happen each second, while radians measure the angle of those cycles. Multiplying Hz by 2π converts the cycles into radians, representing the total angle covered per second in rotational terms.
Can I convert any Hz value to radians just by multiplying by 2π?
Yes, because 1 Hz equals 2π radians per second, so any frequency in Hz can be converted to radians per second by multiplication. This applies to all frequencies regardless of size.
What is the significance of radians in oscillations?
Radians provide a way to measure the angular displacement during oscillations or rotations, allowing for precise calculations of phase, amplitude, and timing in wave and circular motion analysis.
