By making the axes of a pendulum similar to the one described in the preceding section in the shape of knife-edges it is possible to measure the length of this form of pendulum (Kater's) very accurately. The distance between the knife-edges being the length of a simple pendulum that vibrates in the same time, it can be substituted for I in Formula 26, from which

By substituting also the time t determined by experiment, the value of g is determined.
