`T = 2pisqrt(L/g)`

Enter a value for all fields

The **Period of a Pendulum** calculator computes the period (**T**) of a simple pendulum based on the length (**L**) of the pendulum arm and the acceleration due to gravity (g).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**L**) This is the length of the pendulum - (
**g**) This is the acceleration due to gravity.

**Period (T):** The calculator returns the period (**T**) in seconds. However this can be automatically converted to other time units via the pull-down menu.

The formula is accurate given that the amplitude is small. The formula uses the acceleration due to gravity (9.80665 m/s²).

The formula for the period of a simple pendulum is:

`T = 2π sqrt(L/g)`

where:

- T is the period of the pendulum
- L is the length of the pendulum
- g is the acceleration due to gravity
