Dimensional formula of coefficient of linear expansion

Coefficient of linear expansion
[K−1]
Written in full: [M⁰ L⁰ T⁰ A⁰ K⁻¹]

How to derive it

Coefficient of linear expansion = Change in length ÷ (Original length × Temperature change)

Put in the dimensions of each part: [L] ÷ ([L] × [K]) = [K⁻¹].
