# Units for Period of Pendulum Formula

1. Jun 8, 2006

### Lobdell

I found the formula for the period of a pendulum:
---
T = 2∏√( L / g)
T: Time
L: Length of Pendulum
g: Gravitational Force
---
However, I couldn't find information about the units! If somebody could provide me with information regarding this, it'd be greatly appreciated. Thanks

The units don't matter as long as they're consistant.

(That is, if g is in m/s2 then L should be in meters and T will be in seconds.

g is the acceleration due to gravity (not gravitational force), and thus (as dav2008 explained) has units of acceleration, not force.
