Common mistakes
-
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.
