What is Length ?

Length is a measure of distance commonly understood to mean the most extended dimension of an object. It is a term used to identify the size of an object or the distance between two points. In most systems of measurement, such as SI Units or the Imperial system, a base unit for length is chosen, from which all other units are derived. In the International System of Units (SI) system the base unit for length is the metre. The metre is currently defined as the length of the path traveled by light in a vacuum in 1/299,792,458 of a second.
