Dimension of Work = Dimension of Energy. Work = Force × distance. Force = mass × acceleration. Dimension of mass = [M], length = [L], time = [T]. Dimension of acceleration = [LT⁻²]. Dimension of force = [MLT⁻²]. Dimension of energy = [ML²T⁻²].
In terms of basic units of mass (M), length (L) and time (T), dimension of energy is
