Definition
The linear mass density of a one-dimensional body is its mass per unit length.
Symbol
The usual symbol used to denote linear mass density is $\mu$ (Greek letter mu).
Sometimes $\lambda$ (Greek letter lambda) is also used.
Dimension
The dimension of linear mass density is $\mathsf M \mathsf L^{-1}$: mass per unit length.
Units
- The SI units of linear mass density are $\mathrm {kg} \ \mathrm m^{-1}$ (kilograms per metre).
- The CGS units of linear mass density are $\mathrm g \ \mathrm{cm}^{-1}$ (grams per centimetre).
Thus:
- $1 \ \mathrm{kg} \ \mathrm m^{-1} = 10 \ \mathrm g \ \mathrm{cm}^{-1}$
Also known as
Linear mass density is usually referred to just as linear density when it is clear that mass density is the kind of density under discussion.
