What is the BTU to Kilojoules Converter?
The British Thermal Unit (BTU) to Kilojoules (kJ) converter is an international HVAC tool. It translates traditional American heating and cooling capacities (BTUs) into the standard metric unit (kJ) used by mechanical engineers in the rest of the world.
How It Works (Formula)
In thermodynamics, a single BTU is slightly larger than a Kilojoule. Exactly 1 BTU equals 1.05505585 Kilojoules. To convert to the metric system, the calculator simply multiplies your inputted BTUs by this 1.055 constant.
$$ E_{(\text{kJ})} = E_{(\text{BTU})} \times 1.05505585262 $$
The thermodynamic multiplication mapping US heating units to metric engineering.
How to Use It
Input the commercial heating or cooling rating in BTUs. The calculator will instantly multiply the value by the 1.055 thermodynamic constant and output the exact metric equivalent in Kilojoules (kJ). For example, 1,000 BTUs is exactly 1,055 kJ.
