The formula to calculate BTU from Kilojoules (kJ) is:

\[ E (\text{BTU}) = E (\text{kJ}) \times 0.947817 \]

Where:

Kilojoules to BTU Definition

Joule (J) is a unit of energy, representing the amount of work done when a force of one newton displaces an object by one meter. Kilojoule (kJ) is a unit of energy, representing 1000 joules. 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. The conversion from kilojoules to BTU is straightforward: multiply the energy in kilojoules by 0.947817.

Example Calculation

Let's assume the following value:

Using the formula:

\[ E = 5 \times 0.947817 \]

\[ E = 4.739085 \text{ BTU} \]

The Energy (BTU) is 4.739085 BTU.
