speed = distance / time

acceleration = [ speed ] / time = [ distance / time ] / time = distance / time^{2}

force = mass * [ acceleration ] = mass * [ distance / time^{2} ] = mass * distance / time^{2}

work = [ force] * distance = [ mass * distance / time^{2} ] * distance = mass * distance^{2} / time^{2}

power = [ work ] / time = [ mass * distance^{2} / time^{2} ] / time = mass * distance^{2} / time^{3}

Mass is measured in kilograms.

Distance is measured in meters.

Time is measured in seconds.

power = mass * distance^{2} / time^{3} = mass * distance^{2} * time^{-3} = kg * m^{2} * s^{-3}

power = kg * m^{2} * s^{-3}
