A Rod A rod is a unit of distance equal to 5.5 yards or 16.5 feet.
Until fairly recently there was only one thing that was exactly one meter long. It was the prototype meter, a rod of platinum that was by definition exactly one meter. The unit itself was originally based on the length of a pendulum that swings with a given frequency, so it wasn't chosen based on some every day object of the given length.
