Energy Converter

Convert between various units of energy, including joules, calories, kilowatt-hours, and more.

Energy is the capacity to do work or produce heat. It is a fundamental concept in physics and is used in various fields such as engineering, chemistry, and environmental science. Understanding energy measurements is crucial for tasks like calculating the energy consumption of appliances, determining the caloric content of food, or designing renewable energy systems.

Examples of real-world applications:

  • Calculating the energy consumption of household appliances to manage electricity usage.
  • Determining the caloric content of food for dietary planning and nutrition.
  • Designing and optimizing renewable energy systems such as solar panels and wind turbines.

How to Convert Joules to Calories

Divide the number of joules by 4.184 to get calories.

calories = joules ÷ 4.184

Example: 1000 J ÷ 4.184 = 239 cal

How to Convert Calories to Joules

Multiply the number of calories by 4.184 to get joules.

joules = calories × 4.184

Example: 100 cal × 4.184 = 418.4 J

How to Convert kWh to Joules

Multiply the number of kilowatt-hours by 3,600,000 to get joules.

joules = kWh × 3,600,000

Example: 2 kWh × 3,600,000 = 7,200,000 J
