Units for Period of Pendulum Formula

  1. Jun 8, 2006 #1
    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 :cool:

    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.
