Enter the acceleration due to gravity (m/s^2) and the frequency (hz) into the Pendulum Length Calculator. The calculator will evaluate the Pendulum Length.

## Pendulum Length Formula

The following two example problems outline the steps and information needed to calculate the Pendulum Length.

PL = g / (4*pi^2*f^2)

• Where PL is the Pendulum Length (m)
• g is the acceleration due to gravity (m/s^2)
• f is the frequency (hz)

## How to Calculate Pendulum Length?

The following example problems outline how to calculate Pendulum Length.

Example Problem #1:

1. First, determine the acceleration due to gravity (m/s^2).
• The acceleration due to gravity (m/s^2) is given as: 9.81.
2. Next, determine the frequency (hz).
• The frequency (hz) is provided as: 2.
3. Finally, calculate the Pendulum Length using the equation above:

PL = g / (4*pi^2*f^2)

The values provided above are inserted into the equation below and computed.

PL = 9.81 / (4*pi^2*2^2) = .062 (m)

Example Problem #2:

For this problem, the variables required are provided below:

acceleration due to gravity (m/s^2) = 9.81

frequency (hz) = 3
