1 joule = 1 watt-second
kilo = 1,000
hour = 3,600 seconds
1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules

How many joules is 1 kWh equal to?
1 kwh = 3,600,000 Joules
How many joules of energy is there in kwh of energy?
1 joule = 1 ws (watt-second); since 1 kw = 1000 w, and 1 h = 3600 seconds, it follows that 1 kwh = 3,600,000 ws or joule.
How many joules of energy is in a lighted match?
Depending on the power of the lighting system; 1 joule (J) = 2,777 778.10-7 kWh.
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 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 is 1 kWh equal to?

How many joules of energy is there in kwh of energy?
1 joule = 1 ws (watt-second); since 1 kw = 1000 w, and 1 h = 3600 seconds, it follows that 1 kwh = 3,600,000 ws or joule.
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 Therms per kWh?
A therm is an energy unit (equal to 100000 BTU) while kilowatts are power (energy/time). 1 watt = 1 Joule/second, and 1 kilowatt = 1000 Joules/second. The kilowatt hour is an energy unit (power X time = energy). 1 therm = 29.31 kWh
What units are used in electric utilities?
Kilowatt-hour (KWh) which is an energy unit equivalent to a power of 1000 Watts running for 1 hour = 1000x3600 Joules =3.6million Joules. 1 kWh is sometimes called in the trade " 1 unit".
Write a relation between commercial unit of electricity and the SI unit of energy?
1 kWh = 3,600,000 joules (or watt-seconds).
How many joules in one kilowatt?
1 kWh = 3.6 x 106 joules. In engineering notation, that's 3.6E6.
How many joules of energy is in a lighted match?
Depending on the power of the lighting system; 1 joule (J) = 2,777 778.10-7 kWh.
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 Kilowatt Hours are in 1 million BTUs?
1 kWH = 3.6 megajoules of energy and 1 BTU = approximately 1055 joules.1 kWH = 3412.3 BTUSo a million BTUs would be 3.4123 billion BTUs (3.4 x 109 BTU)However, this is not an exact conversion because kWH is energy exerted over time, while BTU is energy content.(see the related question)
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 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
