BTU to Kilojoule (kJ) Converter

The Conversion Formula

The formula for converting British Thermal Units (BTU) to kilojoules (kJ) is:

Where:

• E_kJ: Energy in kilojoules (kJ)
• E_BTU: Energy in British Thermal Units (BTU)
• 1.055056: The conversion factor from BTU to kJ

About BTU and Kilojoules

The British Thermal Unit (BTU) and kilojoule (kJ) are both units of energy, but they are used in different contexts:

• 1 BTU is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at sea level.
• 1 kilojoule is equal to 1000 joules, where a joule is defined as the amount of energy transferred when a force of 1 newton acts over a distance of 1 meter.
• 1 BTU ≈ 1.055056 kJ

BTUs are commonly used in the United States for measuring heat energy, especially in heating and cooling systems. Kilojoules, being part of the metric system, are more widely used internationally and in scientific contexts.
