Length, abbreviated as l, also called distance, is the dimension from one point to another point or the dimension from one end to the other end of an object.

## Length formula

$$\large{ \Delta l = l_f - l_i }$$
Symbol English Metric
$$\large{ \Delta l }$$ = length differential $$\large{ft}$$  $$\large{m}$$
$$\large{ l_f }$$ = final length $$\large{ft}$$ $$\large{m}$$
$$\large{ l_i }$$ = initial length $$\large{ft}$$ $$\large{m}$$
