Explanation:
Angle is defined as the ratio of length of arc to radius.
Mathematically,
Angle = Length of Arc / Radius
Dimensional formula of Length = M0L1T0
Dimensional formula of Radius = M0L1T0
Substituting in the above formula we get,
Dimensional formula of Angle = M0L0T0. We can also say Angle is dimensionless quantity.
SI unit of Angle is radian (rad)
