Energy Converter

About This Tool

This Energy Converter is a vital tool for professionals and students in science, engineering, and nutrition. Energy, in physics, is the capacity to do work. The base unit for all calculations is the joule (J), the standard SI unit of energy.

The tool facilitates conversions between a diverse set of energy units, including those used for electricity consumption (kilowatt-hours), heat (BTUs), nutrition (calories), and high-energy physics (electron-volts). It provides the precision needed to move between different fields of study and practical applications, from calculating your electricity bill to understanding the energy content of food.

Tips & Features

• The Joule Standard: All energy units are converted by relating their value to the joule (J). A joule is defined as the work done when a force of one newton is applied over a distance of one meter.
• Nutritional vs. Thermochemical Calories: Be aware that a 'Calorie' (with a capital C) used in nutrition is actually a kilocalorie (kcal), which equals 1,000 'small' calories (cal) used in chemistry. This tool includes both.
• BTU (British Thermal Unit): This is a traditional unit of heat energy, defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It's commonly used in HVAC and heating applications.
