Definition:Linear Measure

Definition
Linear measure is the means of measurement of physical displacement.

Dimension
Linear measure is one of the fundamental dimensions of physics.

In dimensional analysis it is assigned the symbol $L$ or $\mathbf L$.

Units

 * The SI unit of linear measure is the meter $\mathrm m$.
 * The CGS unit of linear measure is the centimeter $\mathrm {cm}$.

Thus:
 * $1 \ \mathrm m = 10^2 \ \mathrm {cm} = 100 \ \mathrm {cm}$

Distance
The term distance has a specialized meaning in analysis which has an immediate practical application in analytic geometry.
