Heat Energy Unit Converter

Our heat energy converter allows precise conversion between different units of thermal energy, including joules, calories, kilocalories, British Thermal Units (BTU), and kilowatt-hours.

What is Heat Energy?

Heat energy is a form of energy that transfers between systems or bodies due to their temperature difference. It flows naturally from a higher temperature body to a lower temperature body and is measured in various units depending on the application and region.

Common Heat Energy Units

Joule (J)

The SI unit of energy, work, and heat. One joule equals the energy transferred when applying a force of one newton through a distance of one meter.

Calorie (cal)

Originally defined as the energy needed to raise the temperature of 1 gram of water by 1°C. One calorie equals approximately 4.184 joules.

Kilocalorie (kcal)

Equal to 1,000 calories. This is the "Calorie" (with capital C) used in nutrition. One kilocalorie equals approximately 4,184 joules.

British Thermal Unit (BTU)

The amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. One BTU equals approximately 1,055 joules.

Kilowatt-hour (kWh)

A unit of energy equal to 3.6 million joules. Commonly used for electrical energy billing, but also applicable to heat energy measurements.
