The formula to calculate Kilojoules (kJ) from BTU is:
\[ E (\text{kJ}) = E (\text{BTU}) \times 1.055056 \]
Where:
British Thermal Unit (BTU) is a unit of energy, representing the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit. Kilojoule (kJ) is a unit of energy, representing 1000 joules. The conversion from BTU to kilojoules is straightforward: multiply the energy in BTU by 1.055056.
Let's assume the following value:
Using the formula:
\[ E = 5 \times 1.055056 \]
\[ E = 5.27528 \text{ kJ} \]
The Energy (kJ) is 5.27528 kJ.
