Common mistakes

  • Food 'calories' are actually kilocalories: 1 kcal = 1,000 cal. A '500-calorie' meal therefore contains 500 kcal, half a million small calories. Labels write the same thing as 'kcal' or as 'Cal' with a capital C.
  • 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.
