\nOne kilowatt hour (kWh) is a unit of energy. It is the energy consumed by a 1 kilowatt (kW) power device operating for 1 hour (h).
\n<\/section>\n
\n1 kilowatt (kW) = 1000 watts (W) = 1000 joules per second (J\/s).
\n1 hour (h) = 60 minutes \u00d7 60 seconds = 3600 seconds (s).
\n<\/section>\n
\nTherefore, 1 kWh = 1 kW \u00d7 1 h = (1000 J\/s) \u00d7 (3600 s) = 3,600,000 J.
\nIn scientific notation, this is $3.6 \\times 10^6$ J, which is equal to $36 \\times 10^5$ J.
