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.
-
The 'BTU' rating on AC units and heat pumps almost always means BTU per hour, a power, not an amount of energy. A '12,000 BTU' unit delivers about 3.5 kW of cooling continuously, not a fixed energy budget. Compare via 1 kW ≈ 3,412 BTU/h.
