The formulas are
W = Fd (work = force x distance)
P = W/t (power = work divided by time) and W = Pt
Which means that
P = Fd/t (power = force x distance divided by time)
The SI unit of power, the watt, equals 1 newton-meter/sec (1 joule/sec).

Work is typically measured in Joules (J) or foot-pounds (ft-lb) in the International System of Units (SI) and Imperial system, respectively. Work is defined as the energy transferred when a force acts over a distance.
work is equivilant to the energy expended in achieving it. The answer should be joules
work and energy +++ The Joule (J) is the unit of energy, alone, not of work. The Watt (W) is the unit of power, i.e. work done in converting or transferring energy, and 1W = 1J/s.
The unit of measure for work output is the joule (J).
The unit used to measure chemical energy is the joule (J) or the calorie (cal).
The metric unit of length is the 'meter'.
The SI unit of voltage is the Volt, which is a derived unit equivalent to a Joule/Coulomb.
