To calculate the kilowatt-hours used, you need to convert the watts to kilowatts by dividing by 1000, then multiply by the hours the appliance was used. 1500 watts = 1.5 kilowatts 1.5 kW x 0.167 hours (10 minutes converted to hours) = 0.25 kWh So, the appliance would use 0.25 kilowatt-hours if used for 10 minutes at 1500 watts.
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
To convert kilowatt-hours (kWh) to watts, you need to multiply by 1000. So, 1209 kWh is equal to 1209,000 watts.
1 kilowatt = 1000 watt ==> 1 watt = 0.001 kilowatt
Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?' For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.
To calculate the kilowatt-hours used, you need to convert the watts to kilowatts by dividing by 1000, then multiply by the hours the appliance was used. 1500 watts = 1.5 kilowatts 1.5 kW x 0.167 hours (10 minutes converted to hours) = 0.25 kWh So, the appliance would use 0.25 kilowatt-hours if used for 10 minutes at 1500 watts.
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
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.
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
746 watts = 1 horsepower 1,000 watts = 1.3405 horsepower (rounded) 1 kilowatt-hour = 1.3405 horsepower-hour (rounded)
Kilo means thousand. There are 1000 watts in a kilowatt.
To convert kilowatt-hours (kWh) to watts, you need to multiply by 1000. So, 1209 kWh is equal to 1209,000 watts.
1 kilowatt = 1000 watt ==> 1 watt = 0.001 kilowatt
To calculate the kilowatt hours (KWh) used to light a 30 watt light bulb for 1 hour, you would divide the wattage (30) by 1000 to get the kilowatt value (0.03). Then, multiply this by the number of hours (1) to get 0.03 KWh.
Watts does not have a time component to it; so you should have asked, "How many kilowatt-hours does an oven use per hour?' For example, if the oven uses 1600 watts, then in one hour, it would use 1600 watt-hours, or 1.6 kilowatt-hours.
