- 1. Convert 1 kWh to the J base: 1 × 3,600,000 = 3,600,000 J.
- 2. Convert from J to BTU: 3,600,000 ÷ 1,055.05585262 = 3,412.141633 BTU.
- 3. Direct factor check: 1 × 3,412.14163313 = 3,412.141633 BTU.
Energy and power are different quantities: kWh is energy, while kW is a rate of energy transfer. “Food Calorie” means kilocalorie (kcal) here.
