Common mistakes

  • Kilowatts (kW) and kilowatt-hours (kWh) are constantly confused: kW is power, how fast energy is being used right now, while kWh is an amount of energy, power times time. A 2 kW heater running for 3 hours uses 2 × 3 = 6 kWh. Your electricity bill counts kWh; your main fuse limits kW.
  • The relationship is exact: 1 kWh = 3.6 MJ (3,600 kJ, because an hour has 3,600 seconds). The common slip is dividing when you should multiply: 10 kWh is 36 MJ, not 2.8. Remember the direction: kWh → MJ means times 3.6.
