Dimensional formula of weight

Weight
[M L T−2]
Written in full: [M¹ L¹ T⁻² A⁰ K⁰]

How to derive it

Weight = Mass × Acceleration due to gravity

Put in the dimensions of each part: [M] × [LT⁻²] = [M L T⁻²].

SI unit

The SI unit of weight is newton (N).

Same dimensions as weight

These quantities have exactly the same dimensions, a favourite trick in JEE and NEET "which pair has the same dimensions" questions:
