1 kwh = 3,600,000 Joules
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
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
1 Joule = 1 watt-second, therefore, you divide by 3,600,000.
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.
1 kwh = 3,600,000 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.
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.
The electric meter uses kWh (kilowatt x hours) as units; a Joule is a watt x second. Therefore, a kWh has 3.6 million joules. Just multiply by this number.
1 kWh = 3.6 x 106 joules. In engineering notation, that's 3.6E6.
A Joule is a Watt-second (or W=J/s). Therefore, 3.5 kWh = 3.5*3600 kWs = 3.5*3600*1000 W-s = 12.6 million Joules
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
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".
The energy 1 kilowatt-hour (kWh) is 3600000 joules.AnswerThere is no such thing as a 'kilowatt per hour'. You probably mean 'kilowatt hour'?
A kilowatt hour is a metric unit, although it is a slightly confused one. A watt is one joule per second. This means that 1 kWh is 1000 joules multiplied by 360 seconds (1 hour) per second. So 1 kWh is 360 kilojoules.661 kWh is 661 times 360 kilojoules, which is 237960 kilojoules, or 237.96 megajoules.
1 Joule = 1 watt-second, therefore, you divide by 3,600,000.
1 Kilo Joule = 2.777778e-007 Kwh/kg
