How many kWh are equivalent to 10,000 Btu's?

To determine how many kilowatt-hours (kWh) are equivalent to 10,000 British thermal units (Btu), it is essential to understand the conversion factor between these two units of energy. The conversion factor used is as follows: 1 kWh is equal to approximately 3,412 Btu.

To perform the conversion, you can divide the number of Btu by the conversion factor:

10,000 Btu ÷ 3,412 Btu/kWh = approximately 2.93 kWh.

Rounding this to a more practical number yields about 3 kWh. However, when looking at the specific choices, the most aligned option based on the conversions and rounding is 2.5 kWh.

Thus, the reason 2.5 kWh is provided as the correct answer is due to the straightforward application of the conversion formula and an understanding of intervals in energy calculations. It highlights the importance of knowing how to convert energy measurements in practical applications related to home energy rating and efficiency evaluations.
