To calculate the kWh for a specific appliance, multiply the power rating (watts) of the appliance by the amount of time (hrs) you use the appliance and divide by 1000. This 60-watt lightbulb that we used for 90 hours in a month when we were charged $0.09/kWh cost us approximately 50 cents for the month.
How many watts are used in an hour?
A kilowatt-hour is 1,000 watts used for one hour. As an example, a 100-watt light bulb operating for ten hours would use one kilowatt-hour.
How much is 1000 watts per hour?
Common Watts to Kilowatt-Hour Conversions Power in Watts Energy in Kilowatt-hours Electricity Cost 700 W 0.7 kWh $0.084 per hr 800 W 0.8 kWh $0.096 per hr 900 W 0.9 kWh $0.108 per hr 1000 W 1 kWh $0.112 per hr.
How do I calculate watts?
Steps The number of watts is equal to amps multiplied by volts. That’s it! For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power). This is why watts are sometimes called volt-amps.
How do you calculate watts per hour in the Philippines?
Multiply the wattage by the average number of hours the device is used per day. Let’s say you use a 100-watt electric fan for 10 hours per day. Multiplying 100 watts by 10 hours will result in 1,000 watt-hours—that’s how much your electric fan consumes in a day.
How do you calculate electricity from watts?
All you need to enter is: 1) How much power the appliance draws in Watts. You can find this on most compliance plates, as pictured here. 3) An estimate of how often the appliance is used. Electricity Usage Per Year = (Watts / 1000) * Hours/Day * Days/Week * Weeks/Year = kWh/year.
How much does 1 watt per hour cost?
The average cost of a kilowatt hour in the US is between 9 and 10 cents. We’ll round up and call it 10 cents. So, if one watt burns up 8.76 kwh in a year, it will cost you 87.6 cents on your electric bill every year.
How much watts does A fridge use?
The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it. Different types of fridges have different power requirements.
How do I calculate unit per hour?
Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
How do you convert watts to kilowatts per hour?
Here’s the Formula for Calculating Watts Into Kilowatt-Hours: kWh = (watts × hrs) ÷ 1,000.
How do I calculate the wattage of my house?
The same formula can be used to determine the capacity of the house’s overall electrical service. Because a home’s main service is 240 volts, the math looks like this: 240 volts x 100 amps = 24,000 watts. 80 percent of 24,000 watts = 19,200 watts.
How much is 1 kWh in the Philippines?
Meralco announced Monday a downward rate adjustment of ₱0.0746 per kilowatt-hour (kWh) for January, yielding a monthly overall rate of ₱9.7027 per kWh.

How much electricity does 240V use?
To determine watts, we have to multiply the voltage by the amperage. The 120V 3/4HP J unit pulls 7.3 amps at 120V so the wattage is 876 watts. The 240V 3/4HP J unit pulls 3.65 amps at 240V so the wattage is 876 watts. The wattage is the same for both 120V and 240V, so the cost to run them would also be the same.
How much is 1500 watts per hour?
