# What is Dimensional Formula of Linear Mass Density?

Posted in Dimensional Formulae | Email This Post |Linear Mass Density is defined as measure of mass per unit of length.

Mathematically,

**Linear Mass Density = Mass / Length.**

Dimensional Formula of Mass = M^{1}L^{0}T^{0}.

Dimensional Formula of Length = M^{0}L^{1}T^{0}.

Putting these values in above equation we get,

**Dimensional Formula of Linear Mass Density = M ^{1}L^{-1}T^{0}.**

SI unit of Linear Mass Density is kg m^{-1}.

Please note : Linear mass density is the quantity of mass per unit length. Here length is a simple metre quantity. Linear densities are basically used for long thin objects. Please do not get confused between Linear mass density and density.

plzzz check your length formula

I think its wrong length formula is (L3)

Thanks for checking

Hi, Sorry you are wrong, Length formula is just L and not L

^{3}in this formula we are talking about length which L and L3 is formula of volume

hey..a problem with your length

In linear mass density the length is L whereas in volumetric mass density it can be L3.
