How many BTUs are in one cubic foot per hour (CFH)?

• A. 500 BTU
• B. 1000 BTU
• C. 1500 BTU
• D. 2000 BTU

Answer: (B)

One cubic foot per hour (CFH) is commonly used to measure the flow of gas, and the conversion of CFH to BTUs (British Thermal Units) helps in understanding the energy value of the gas being consumed. For natural gas, which is most commonly used in residential applications, one cubic foot of gas typically contains about 1,000 BTUs. This relationship is rooted in the energy content of natural gas, which can vary slightly based on impurities and other factors, but the standard conversion factor accepted in industry practices is around 1,000 BTUs for one cubic foot of natural gas consumed per hour. Understanding this conversion is vital for adequately sizing appliances, ensuring proper gas line specs, and calculating overall heating efficiency. In contrast, other figures provided do not align with the standard energy content for natural gas, making them incorrect for this particular unit conversion. Thus, recognizing that one cubic foot per hour corresponds to 1,000 BTUs is essential for anyone working with gas systems in plumbing or HVAC contexts.
