The formula to calculate Kilowatt-hours (kWh) from BTU is:
\[ E (\text{kWh}) = E (\text{BTU}) \times 0.00029307107017 \]
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. Kilowatt-hour (kWh) is a unit of energy, representing the amount of energy used when a device with a power of one kilowatt operates for one hour. The conversion from BTU to kilowatt-hours is straightforward: multiply the energy in BTU by 0.00029307107017[^1^].
Let's assume the following value:
Using the formula:
\[ E = 5000 \times 0.00029307107017 \]
\[ E = 1.465355 \text{ kWh} \]
The Energy (kWh) is 1.465355 kWh.
