# What is Dimensional Formula of Heat?

Posted in Dimensional Formulae | Email This Post |Heat is defined as the form of energy that is transferred across the boundary of a system at a given temperature to another system at a lower temperature by virtue of the temperature difference between the two system.

Mathematically,

**Heat = Energy**

Dimensional formula of Energy = M^{1}L^{2}T^{-2}

Putting these values in above equation we get,

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

SI unit of Heat is Joule (J)
