KWH is standard unit used to measure electrical energy. simply put, 1kwh is the amount of energy used by a 1KW appliance when it works continuously for 1hour. if the appliance is only 100watts, i.e, 0.1Kw, it takes 10hours for it to expend 1kwh of energy. in other words, it uses0.1KWH of energy per hour.
