A kilowatt (1000 watts) is the unit of measurement for the current consumed per hour.
The standard unit is the ampere, commonly called "amp", symbol 'A'.
A unit is not used to measure power, but energy.A unit is used by British electrical companies to measure energy consumption, and is short for 'Board of Trade Unit'. A unit is equivalent to a kilowatt hour. A watt, on the hand, is used to measure power, not energy -so you cannot relate a unit to a watt.
'Electricity' is not a quantity, so cannot be measured and, therefore, has no unit of measurement. It is the name of a field of study, just like 'chemistry', etc.A 'unit' of electrical energy is short for 'Board of Trade Unit' (a former government organisation that, at one time, set energy prices in the UK), and is exactly equivalent to a kilowatt hour, which is defined as the amount of energy consumed, over a period of one hour, at a rate of one kilowatt. A unit or kilowatt hour is equal to 3.6 million joules (a joule being the SI unit for energy), and normally costs around £0.15 to buy.
The "anemometer" is an instrument used to measure wind speed. Its output is a speed measurement, and may be expressed in any convenient unit of speed, such as 'miles per hour', 'kilometers per hour', 'feet per second', etc. Anemometers are sold in units of "each".
Well 1 KWh is "1000 watts per hour". So if you have 400w per hour take400watts per hour divided by 1000 and it shows that you get "0.4KWh".AnswerThere is no such thing as a 'kilowatt per hour', which is why the unit of measurement is a 'kilowatt hour', and NOT a 'kilowatt per hour'!.To determine the number of kilowatt hours of energy consumed by the lamp, multiply its power, expressed in kilowatts, by the length of time it is in use. For your example, the answer is 0.4 kWh.
The SI unit of energy is Joules The commercial unit of energy is KiloWaltHour(KWh) The relationship between SI unit and commercial unit is: 1 KWh=3.6*106J (or 3600000 J) One KiloWaltHour is: 1kWh = 1kW * 1h And the definition for kWh is: 1kWh is the electric energy consumed by an appliance of power 1 whenit is used for one hour
Amp
resistance to an electrical current
the symbol of current density is 'J'. & its unit is (Amp/m^2)
An hour is a unit of time measurement equal to 60 minutes, or 3600 seconds.
Current is measured in Amperes in all systems of measurement.
A coulomb is a unit for measurement of electrical charge and an ampere is the unit used for measurement of electric current.
Current.
Electricity consumption or, more accurately, energy consumption is measured in units called joules (J), although electricity supply companies use a bigger, non-SI, unit called the kilowatt hour. A kilowatt hour is defined as 'the energy consumer, over a period of one hour, at the rate of one kilowatt'.

The unit of measure for current load is amperage, or simply amps.
