The unit kWh is a unit of energy, which is power multiplied by time. Multiply the power of the equipment (measured in W or kW) by time used (measured in h) and you get the energy in kWh.
Examples:
A power of 1 kW over a time of one hour is one kWh. A 100 W (0.1 kW) bulb left on for 5 hours uses 0.1 x 5 = 0.5 kWh.
If your home uses an average of 500 W (0.5 kW) then it will consume 12 kWh per day (24 h).
Also not the correct capitalization. Only the W (watt) is capitalized, the k (kilo = 1000) prefix and the time unit h (hour) are not.
Simply, multiply power (kW) from the time (in hours) the equipment has been used..
P (kW) x t (h) = Pt (kWh)

A kilowatt hour measures the amount of energy consumed, at a rate of one kilowatt, over a period of one hour.
To determine the average power (rate of energy consumption), in kilowatts, you must divide the amount of energy consumed, in kilowatt hours, by the number of hours over which that amount of energy was consumed.
A kilowatt hour is the unit for work, used by electricity companies for the purpose of billing its customers. It's correct symbol is: kW.h.
A kilowatt hour is the product of an appliance's power, expressed in kilowatts, and the time for which it operates, expressed in hours.
Mulitply kW by time (in hours). kW is a measurement of power; kWh is a measure of energy (power x time). 1 kW used for 1 minute is 1/60th of a kWh.
To convert 'kwh' to 'kvah' you first need to measure the length of time. You will then convert this amount to hours by dividing by 3,600. You will then divide this amount by the length of time.

A 1000 watt device operated continusouly for 1 hour would equal 1 Kwh.
KWH = KW times hours If you run a 750 KW load (lights, motors, so forth) for 1 hour, you have 750 KWH. If you run it for 1/2 hour, 750 KW X .5 hours = 375 KWH. If you run it for 5 hours, 750 KW X 5 = you do the math.
To reduce kWh by capacitor is when a motor is put in. The terminal voltage is reducing and current is increasing it is connected parallel with the motor.
