# What is Dimensional Formula of Angular Displacement?

Posted in Dimensional Formulae | Email This Post |Angular displacement is defined as the ratio of length and radius.

**Angular displacement= Length/Radius**

Now we know

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

Dimensional Formula of Radius = M^{0}L^{1}T^{0 }—- Radius is related to length.

So

**Angular displacement= M ^{0}L^{1}T^{0}/M^{0}L^{1}T^{0}**

**Hence Dimensional Formula of Angular displacement = M ^{0}L^{0}T^{0}**

**SI units of Angular displacement is radian**
