How many joules is 1 kWh equal to?
1 kwh = 3,600,000 Joules
Convert joules to kwh?
To convert Joules to kilowatt-hours (kWh), divide the number of Joules by 3,600,000 (the number of Joules in a kWh). For example, to convert 1,000,000 Joules to kWh, you would divide 1,000,000 by 3,600,000 to get approximately 0.278 kWh.
How many joules are in a kWh?
1 kWh = 1,000 watt-hour1 watt = 1 joule per second1 hour = 3,600 seconds(1,000 watt-hour) = (1,000 joule/second) x (3,600 second/hour) = 3,600,000 joules
How many joules are in 2 kWh?
7.2×106 J. 1 kWh is equal to 3.6×106 J, and 1 J is equal to 2.778×10-7 kWh. 2 kWh is about 1/18 the amount of energy released from the combustion of a gallon of gasoline, and about 1.6 times the amount of energy released by the detonation of one kilogram of TNT. As of November, 2010, that amount of energy would cost about $0.36 to a resident of New York -- up from about $0.26 in 1990.
How many joules are in different units of energy?
1 calorie = 4.184 joules 1 kilowatt-hour (kWh) = 3.6 million joules 1 British thermal unit (BTU) = 1,055 joules

How you can convert kWh into joules?
1 KWh is 1000 joules- hours per second so you change hours to seconds to get; 1 KWh = 1000 x 3600 joules - sec per sec which is 3600000 joules.
How many kw in a kj?
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.

How many joules of energy are in 1 kWH?
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
A certain household has consumed 250 units of energy during a monthhow much energy is this in joules?
To convert from energy units (kWh) to joules, you can use the conversion factor: 1 kWh = 3.6 × 10^6 joules. Therefore, 250 kWh is equal to 9 × 10^8 joules.
How much is 4180J in kw?
To convert joules to kilowatts, you need to divide the energy in joules by 3,600,000 (since 1 kWh = 3,600,000 J). Therefore, 4180 J is 0.00116 kWh.
Write a relation between commercial unit of electricity and the SI unit of energy?
1 kWh = 3,600,000 joules (or watt-seconds).
Why do energy companies use kWh for bills instead of joules?
Energy companies use kilowatt-hours (kWh) instead of joules because kWh is a more convenient and practical unit for measuring the amount of energy consumed by households and businesses. Joules are much smaller units, requiring large numbers for typical energy usage, whereas kWh provides a more manageable figure for billing purposes.
