You multiply the power by time, ie kW*h
Use the equation. Kw x Hours = KWh so take 10Kw multiplied by 8,760 hours and you get 87,600 KWh. 10Kw x 8,760 hours = 87,600 KWh
To calculate the total electricity usage in 24 hours, you multiply the wattage by the number of hours: 820 watts * 24 hours = 19680 watt-hours or 19.68 kWh. To convert that to kilowatt-hours, divide by 1000: 19.68 kWh.
First, convert the heater's power usage to kilowatts: 260 watts = 0.26 kilowatts. Next, calculate the energy consumption: 0.26 kW * 4 hours = 1.04 kWh. Finally, multiply the energy consumption by the cost per kWh: 1.04 kWh * $0.20/kWh = $0.208. So, running a 260 watt heater for 4 hours would cost approximately 20.8 cents.
If the generator is rated 40 KW, it doesn't mean the generator pours out 40 KWwhenever it's running. It means you can take as much power as you want from itas long as you don't try and take more than 40 KW for too long, because that couldoverheat or damage the generator.Notice that your 40 KW is just the product of the rated voltage and current:120 V times 333 A = 39,960 watts = nominal "40 KW".We point that out in order to mention that the voltage and current rating of thegenerator are irrelevant to the answer.If you load the generator to its max of 40 KW continuously for 24 hours, thenit delivers (40 x 24) = 960 KWH of energy.
Multiply the gas units (imperial) by 100, then divide by three. This will give you how many kilo watts an hour. If you want a more accurate answers, multiply the gas units by 31.6. For metric metres (cubic meteres) multiply by 11.06 to get KWH
First find how many kw are being used. For example, two items using 0.5 kw each add to 1 kw. Then, multiply by the hours it is being used. If we ran these two items for 1 hour we would end up with 1 kwh.
Use the equation. Kw x Hours = KWh so take 10Kw multiplied by 8,760 hours and you get 87,600 KWh. 10Kw x 8,760 hours = 87,600 KWh
To calculate the energy transferred, use the formula: energy (in kWh) = power (in kW) × time (in hours). A 500-watt television is 0.5 kW, and 30 minutes is 0.5 hours. Thus, energy transferred = 0.5 kW × 0.5 hours = 0.25 kWh.
on idle, probably 0. KWh = KW x time (hours) . eg. 20KW for 5 hours = 100KWh (edit. ignore this answer i do not know what exactingly a idle motor is)
To calculate the total electricity usage in 24 hours, you multiply the wattage by the number of hours: 820 watts * 24 hours = 19680 watt-hours or 19.68 kWh. To convert that to kilowatt-hours, divide by 1000: 19.68 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 find kilowatt-hours (kWh) from kilowatts (kW), you need to multiply the power in kilowatts by the time in hours that the power is used. The formula is: kWh kW x hours. This calculation will give you the total energy consumed in kilowatt-hours.
First, convert the heater's power usage to kilowatts: 260 watts = 0.26 kilowatts. Next, calculate the energy consumption: 0.26 kW * 4 hours = 1.04 kWh. Finally, multiply the energy consumption by the cost per kWh: 1.04 kWh * $0.20/kWh = $0.208. So, running a 260 watt heater for 4 hours would cost approximately 20.8 cents.

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.
Multiply the gas units (imperial) by 100, then divide by three. This will give you how many kilo watts an hour. If you want a more accurate answers, multiply the gas units by 31.6. For metric metres (cubic meteres) multiply by 11.06 to get KWH
Since there are 6366 hours in a year, 1930 kWh is about 0.3 kW per hour. (1930 / 6366)
