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
