speed  =  distance / time

acceleration  =  [ speed ] / time  =  [ distance / time ] / time  =  distance / time²

force  =  mass * [ acceleration ]  =  mass * [ distance / time² ]  =  mass * distance / time²

work  =  [ force]  * distance  =  [ mass * distance / time² ] * distance   =   mass * distance² / time²

power  =  [ work ] / time  =  [ mass * distance² / time² ] / time   =   mass * distance² / time³

Mass is measured in kilograms.

Distance is measured in meters.

Time is measured in seconds.

power  =  mass * distance² / time³   =   mass * distance² * time^-3   =   kg * m² * s^-3

power   =   kg * m² * s^-3
