What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one meter (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).
What is Kilocalories?
Kilocalorie (symbol: kcal) is a unit of energy equal to 1,000 calories or approximately 4,184 joules. It is widely used to express the energy content of foods and beverages and is commonly referred to as the dietary calorie. Learn more about kilocalorie.
