Definition

The linear density of a one-dimensional body is its mass per unit length.


The usual symbol used to denote linear density is $\mu$ (Greek letter mu).

Sometimes $\lambda$ (Greek letter lambda) is also used.


Dimension of Linear Density

The dimension of linear density is $M L^{-1}$: mass per unit length.


Units of Linear Density

Thus:

$1 \ \mathrm{kg} \ \mathrm m^{-1} = 10 \ \mathrm g \ \mathrm{cm}^{-1}$
