About Energy Converter

Energy is a fundamental concept in physics that describes the capacity to do work or produce heat. The joule (J) is the SI unit of energy, defined as the work done when a force of one newton moves an object one meter.

Common Energy Units

• Joule (J): The base unit of energy in the International System of Units (SI). One joule equals the work done when a force of one newton moves an object one meter.
• Calorie (cal): Commonly used in chemistry and nutrition. One calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
• Kilowatt-hour (kWh): Widely used for electrical energy billing. One kilowatt-hour equals the energy consumed by a 1-kilowatt device running for one hour.
• Electron volt (eV): Used in atomic and particle physics. One electron volt is the energy gained by an electron when it moves through an electric potential difference of 1 volt.

Applications

Energy conversions are essential in:

• Physics: Understanding work, heat, and energy transformations
• Chemistry: Chemical reactions and thermodynamics
• Engineering: Power systems and energy efficiency
• Nutrition: Food energy content and metabolism
• Electrical Engineering: Power consumption and generation

Conversion Examples

• 1 joule = 0.239 calories (SI to nutritional unit)
• 1 kilowatt-hour = 3,600,000 joules (Electrical to SI unit)
• 1 calorie = 4.184 joules (Nutritional to SI unit)
• 1 electron volt = 1.602177 × 10⁻¹⁹ joules (Atomic to SI unit)
