How much is KWH?

Answer 1

The notation "2.4 kwh" is a shorthand description for 2,400 Watts of electrical power used within a time interval of one hour.

The letter "k" indicates "kilo", which further indicates a multiplier of 1000.

The letter "w" indicates "Watt", which is a unit of electrical power. Therefore, 2.4 kw is another way to describe 2,400 Watts. A Watt can be calculated from two other electrical quantities: Electrical current (measured in Amperes or "Amps") and electrical potential (measured in Volts). By multiplying these two quantities together (Amps and Volts), a measurement of electrical power, in Watts, can be determined. For example, the motor in a clothes dryer may operate by using 3 Amps of current and 120 Volts. In this case, the motor is said to be consuming 360 Watts of electrical power (3 X 120 = 360), or 0.360 kw or 0.360 Kilowatts (0.360 X 1000 = 360).

The letter "h" indicates a unit of time, in this case "hour". If the motor in the example above continues to operate for one hour, then the motor's total consumption of power is 360 Watt hours or 0.360 Kilowatt hours (wh or kwh). Or, if instead, the motor operates for 3 hours then total consumption is 1,080 wh (360 X 3) or 1.08 kwh (0.360 X 3 = 1.08).
