5 days 12 hours = 5.5 days19,800 / 5.5 = 3,600 watt-hours per day = 150 watts
1 day = 24 hours 2 days = 48 hours 3 days = 72 hours 4 days = 96 hours . . . 306 days = 7,344 hours
There are 24 hours in a day. 80 hours * (1 day/24 hours) = 3.33 days 0.33 days * 24 hours = 7.92 hours 80 hours is equivalent to about 3.3 days, or 3 days and 8 hours.
37 days and 12 hours
To compute the electrical consumption of a device, you need to know the power rating of the device in watts and the duration of use in hours. The formula is Power (in watts) x Time (in hours) = Energy consumption (in watt-hours or kilowatt-hours). You can use this information to estimate the cost of running the device by multiplying the energy consumption by your electricity rate.
To calculate the cost of running the welder, first convert the power consumption from amps to watts using the formula: Watts = Volts x Amps. Then, calculate the daily energy consumption by multiplying the power consumption in watts by the hours used per day. Next, convert the daily energy consumption from watts to kilowatt-hours by dividing by 1000. Finally, multiply the daily energy consumption in kilowatt-hours by the electricity cost per kilowatt-hour to get the daily cost. Multiply the daily cost by the number of days per week to get the weekly cost.
To calculate the monthly cost, first convert the daily usage into monthly usage: 700 watts * 10 hours * 30 days = 210,000 watt-hours or 210 kWh. Then, calculate the monthly cost: 210 kWh * $0.09/kWh = $18.90. So, the monthly cost of using the refrigerator would be $18.90.

Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt. Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant. So... To calculate the kilowatt hours: .1 kilowatts (from above, knowing the energy use of the bulb) Multiplied by 24 hours in a day Multiplied by 30 days... .1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours
60 days is 24x60 hours, so the energy used is 60x24x60 watt-hours, 86400 watt-hours or 86.4 kilowatt-hours or units. If it is a 60-watt incandescent bulb it could be replaced by a 12 watt low-energy bulb, and in the same time that would use only 17.3 units, saving 69 units costing about £10.
To calculate the kilowatt-hours (kWh) used by an air conditioner running 12 hours per day in a month, you would multiply the unit's power consumption in kilowatts by the number of hours and the number of days in a month. Assuming an average of 1.5 kW power consumption, it would be 1.5 kW x 12 hours/day x 30 days = 540 kWh per month.
The watts listed on a light bulb indicate the amount of power it consumes per hour. To calculate the energy usage over a year, you would multiply the wattage by the number of hours the bulb is typically used per day, then by 365 days in a year.
To calculate the energy usage of the light bulb, we first convert the power in watts to kilowatts (60.0 W = 0.06 kW). Then, we multiply the power by the time (0.06 kW * 60 days) to get the total energy consumed in kilowatt-hours. Therefore, the light bulb would use 3.6 kWh of electrical energy if left on steadily for 60 days.
"Watts" is a unit of power, not energy. However, energy consumption is typically measured in kilowatt-hours (kWh) per year. To calculate energy consumption, you would need to know the power consumption in watts of a particular device or system and factor in the hours of operation per year.
1 kilowatt is equivalent to 1000 watts of energy, the average appliance will consume about 52 watts of energy. there for with the power of 200 kilowatts one would have enough power to reach mars in roughly 39 days
