Energy Converter

An Energy Converter is a tool used to convert between different units of energy. Energy is a measure of the capacity to do work and can be measured in various units, depending on the application—whether it's mechanical, electrical, thermal, or chemical energy. Some of the most common energy units include joules, calories, kilowatt-hours (kWh), British thermal units (BTU), and electronvolts (eV).

Common Units of Energy:

1. Joule (J): The SI unit of energy, commonly used in physics and engineering.
2. Kilojoule (kJ): 1,000 joules (J).
3. Calorie (cal): A unit of energy often used in the context of food and nutrition.
   • 1 cal = 4.184 joules (J)
4. Kilocalorie (kcal): Often referred to as a "Calorie" (with a capital C) in food.
   • 1 kcal = 1,000 calories (cal) = 4,184 joules (J)
5. Kilowatt-hour (kWh): A unit of energy commonly used in electrical energy consumption.
   • 1 kWh = 3,600,000 joules (J)
6. British Thermal Unit (BTU): A unit of energy commonly used in heating and cooling systems.
   • 1 BTU = 1,055 joules (J)
7. Electronvolt (eV): A small unit of energy used in particle physics.
   • 1 eV = 1.60218×10−191.60218 \times 10^{-19} 1.60218 × 10 −19 joules (J)
8. Therm: A unit often used to measure natural gas consumption.
   • 1 therm = 100,000 BTU
