Electric energy usage on your electric bill is measured in kilowatt-hours (kWh). This indicates the amount of electrical energy consumed over a period of time.
An imperial unit of energy equal to 750 watts is 0.75 kilowatt-hours (kWh). This means that using 750 watts of power for 1 hour consumes 0.75 kilowatt-hours of energy.
The energy transferred can be calculated by multiplying the power (2400 watts) by the time (1 hour = 60 minutes): Energy = Power x Time. 2400 watts * 1 hour = 2400 watt-hours. To convert watt-hours to kilowatt-hours, divide by 1000: 2400 watt-hours / 1000 = 2.4 kilowatt-hours. Therefore, 2.4 kilowatt-hours of energy is transferred when a 2400 watt washing machine is used for 60 minutes.
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.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
30 minutes is 0.5 hours. 1 kilowatt = 1000 watts, so divide both sides by 1000 and you get .001 kilowatts = 1 watt So 8 watts x 30 minutes = .008 kilowatts x 0.5 hours = .004 kilowatt hours.
300 watts 0.3 kilowatts; 0.3kilowatts X 8 hours 2.4 kilowatt-hours
Power consumption is measured in kilowatt hours.
Well, isn't that a happy little question! To find out how many kilowatt-hours 50 watts used for 12 hours equals, we simply need to do a little math. Since 1 kilowatt is equal to 1000 watts, we can convert the 50 watts to 0.05 kilowatts. Multiplying 0.05 kilowatts by 12 hours gives us a total of 0.6 kilowatt-hours. Happy calculating!
Kilowatts are a measure of electrical power. Kilowatt hours are a measure of how much electrical power has been used.
100 watts × 10 hours = 1000 watt hours = 1 kilowatt hour (= 1 kwh) = 1 unit of electricity.
To convert watts to kilowatt-hours (kWh), you need to divide the wattage by 1000. In this case, 550 watts is equal to 0.55 kilowatt-hours (550 / 1000 = 0.55 kWh).
Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
Think of the names. Watt. Kilowatt hour.A kilowatt is 1000 watts. Multiply 250 watts by (1 kilowatt/1000 watts) , so you have 0.25 kilowatts. Multiply this by how many hours the sound is being produced.
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
Electric energy usage on your electric bill is measured in kilowatt-hours (kWh). This indicates the amount of electrical energy consumed over a period of time.
