Extensive Definition
Length is the long dimension of any object. The
length of a thing is the distance between its ends, its linear
extent as measured from end to end. This may be distinguished from
height, which is vertical
extent, and width or breadth, which are the distance from side to
side, measuring across the object at right angles to the length. In
the physical sciences and engineering, the word "length" is
typically used synonymously with "distance", with symbol l or
L.
Length is a measure of one dimension, whereas
area is a measure of two
dimensions (length squared) and volume is a measure of three
dimensions (length cubed). In most systems of measurement, length
is a fundamental
unit, from which other units are derived.
Units of length
In the physical sciences and engineering, when one speaks of "units of length", the word "length" is synonymous with "distance". There are several units that are used to measure length. Units of length may be based on lengths of human body parts, the distance travelled in a number of paces, the distance between landmarks or places on the Earth, or arbitrarily on the length of some fixed object.In the
International System of Units (SI), the basic unit
of length is the metre and
is now defined in terms of the speed of
light. The centimetre and the kilometre, derived from the
metre, are also commonly used units. In U.S.
customary units, English or Imperial
system of units, commonly used units of length are the inch, the foot,
the yard, and the mile.
Units used to denote distances in the vastness of
space, as in astronomy, are much longer
than those typically used on Earth and include the astronomical
unit, the lightyear, and
the parsec.
Units used to denote microscopically small
distances, as in chemistry, include the micron
and the ångström.
Length of moving rods
In the context of "section": While the length of a resting rod can be measured by direct comparison with a measuring rod, this comparison cannot be performed while the rod is moving. In this case we define its moving length as the distance between its two endpoints at a given instance.If the world lines of
the two endpoints of the rod expressed in the coordinates of an R
\, inertial reference frame are

 \mathbf x_1(t) = (t,x_1(t),y_1(t),z_1(t))\,
and

 \mathbf x_2(t) = (t,x_2(t),y_2(t),z_2(t))\, ,
then the length of the rod in this reference
frame at the t \, instance is

 l_R(t) = \sqrt.
Since in special
relativity the relation of simultaneity
depends on the chosen frame of reference, the length of moving rods
also depends.
