About Kilocalorie (kcal)
A unit of energy equal to 1,000 gram-calories (exactly 4,184 joules). This is the unit behind the "Calorie" (capital C) on US food packaging — a 200-Calorie granola bar contains 200 kcal = 200,000 small calories = 836 kJ. Adult daily dietary intake is typically 1,800–2,500 kcal depending on size and activity. Kilocalories are also used for heating-system output in some parts of Europe and for metabolic rate reporting in physiology.
About Kilowatt Hour (kWh)
The global standard unit of electrical energy billing — equal to a kilowatt of power consumed (or delivered) for one hour, or 3,600,000 joules. Residential electricity bills, utility-scale grid planning, electric-vehicle battery capacities (e.g., Tesla Model 3 = 75 kWh), and home solar production are all quoted in kWh. Typical US household electricity consumption is about 900 kWh per month; EV efficiency is roughly 0.25 kWh per mile.
