# What is Dimensional Formula of Speed?

Posted in Dimensional Formulae | Email This Post |Speed is defined as change of distance per unit time. Speed is a scalar quantity.

Mathematically,

Speed = distance / time .

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

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

Putting these values in above equation we get,

**Dimensional Formula of Speed = M ^{0}L^{1}T^{-1}**

SI unit of Speed is ms^{-1}
