Energy Units Explained

Joule (J)

The joule is a unit of energy commonly used in physics. It represents the work done when a force of one newton moves an object one meter. This is the standard unit in the International System of Units (SI) for measuring energy.

Calorie (cal)

Calories are commonly used to measure food energy. However, in scientific contexts, one calorie represents the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.

Kilowatt-hour (kWh)

The kilowatt-hour is mainly used in the context of electrical energy. It represents the amount of energy consumed by a 1,000-watt appliance running for one hour. You’ll often see it used on electricity bills.

British Thermal Unit (BTU)

BTUs are primarily used in heating and air conditioning systems to represent the energy required to heat one pound of water by one degree Fahrenheit. It’s more commonly used in the United States.

Electron Volt (eV)

In particle physics, the electron volt measures the energy gained by an electron when it moves through an electric potential difference of one volt. It’s a tiny unit of energy used to measure atomic and subatomic processes.

FAQs About Energy Conversion

What is the easiest way to convert joules to calories?

To convert joules to calories, simply multiply the joules by 0.239. For example, 100 joules is approximately 23.9 calories.

How do I convert kilowatt-hours to BTUs?

To convert kilowatt-hours to BTUs, multiply the kilowatt-hours by 3,412. For example, 1 kWh equals approximately 3,412 BTUs.
