# What is Dimensional Formula of moment of couple?

Posted in Dimensional Formulae | Email This Post |Moment of couple is defined as the product of perpendicular distance between the forces and magnitude of the force.

Mathematically,

Moment of couple = Force x Distance

Dimensional Formula of Force= M^{1}L^{1}T^{-2}

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

Putting these values in the given equation we get,

**Dimensional Formula of moment of couple = M ^{1}L^{2}T^{-2}**

SI unit of moment of couple is Newton metre (N m)
