About BTU and kilojoules
The Conversion Formula
To convert BTU to kilojoules, multiply the value by the conversion factor: 1 BTU = 1.0551 kJ. For a worked example, suppose you need to convert 25 BTU to kilojoules: 25 × 1.0551 = 26.3765 kJ. To convert in the opposite direction, divide by 1.0551, or equivalently multiply by 0.947813.
About BTU
The British Thermal Unit (BTU) is the imperial counterpart to the calorie. It is the heat needed to raise 1 pound of water by 1°F. Despite its name, it is almost exclusively used in the United States today, particularly for heating (furnaces) and cooling (air conditioners). BTU are commonly used in AC unit ratings, Gas grills, Furnaces, and Water heaters, Propane tanks.
Burning a single wooden match releases about 1 BTU.
About kilojoules
The kilojoule (kJ) is the standard unit for food energy in most of the world (Australia, Europe, etc.), replacing the Calorie. One food Calorie (kcal) is approximately 4.2 kJ. It provides a more precise measure of energy intake than the large Calorie. kilojoules are commonly used in Food labels (Global), Exercise machines, Diet planning, and Thermodynamics, Metabolic rate tracking.
A slice of bread has about 300-400 kJ.
When Would You Convert BTU to kilojoules?
Converting between btu and kilojoules is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 BTU = 1.0551 kJ) memorized or bookmarked can save time in professional and everyday contexts alike.
