It depends what the power rating of the appliance is. A 500 watt microwave will use half a kilowatt if it's run for an hour on full power. A 750 watt unit will use 3/4 of a unit in the same time period.
I would use a histogram.
Watt hour is a measurement of energy use, something that's pulling one watt during one hour. Tera is a multiplier, 1x10^18, so it's either something pulling one watt for that many hours, or it's something pulling that many watts for one hour or something inbetween.
There are exac- wait I actually want you to figure it out by yourself so try these equations- 60x 24=___. ( because 60 mins in hour and 24 hour day) let's use w for the answer to that problem. So if w=60x 24, then your answer would be this- w x 365=_____? you can use a calculator to figure these out if you want
Both are correct.
Use dimensional analysis/unit analysis/factor label (all different terms for the same concept). 7 miles/second * 60 sec/min * 60 min/hour = 25200 miles/hour

A hair dryer uses about 1 kW, a tumble dryer uses 3 kW.
0.04 kilowatts one kilowatt is 1000 watts
A 400-watt light uses energy at the rate of 0.4 kilowatt. In 1 hour, it uses 0.4 kilowatt-hour of energy.
None. There is no such thing as a 'kilowatt per hour'. If, on the other hand, you are asking how many 'kilowatt hours' a flatscreen television uses, simply look at its nameplate to find its power rating in kilowatts (more likely, it's in watts, so you need to divide by 1000), and multiply it by 1 to find the number of kilowatt hours consumed over a period of one hour.
Anything that uses 40 kilowatts would use 40 kilowatt-hours for each and every hour.
Energy-saving bulbs use much less than 1 kilowatt and most of them use less than 40 watts which is 0.04 kilowatts. A 20 watt bulb uses 1 kilowatt-hour of energy if run for 50 hours.
0.05 to 0.1 kW.
The kilowatts will very depending on the size of the heating element(s) and the size of the pump(s).
To convert kilowatts to amperes, you need to know the voltage of the circuit. Without the voltage, you cannot determine the amperage. Use the formula: Amperes = Kilowatts / Volts.
To calculate the kilowatts per hour used by a 1.5 hp electric motor, you first convert horsepower to kilowatts: 1.5 hp is approximately 1.12 kW (1 hp ≈ 0.746 kW). If the motor runs continuously for one hour, it would consume about 1.12 kWh. However, the actual consumption may vary based on the motor's efficiency and load conditions.
