What is the heating value of butane?

The heating value of butane is generally accepted to be around 3250 BTU/cubic foot when measured at standard conditions. This value represents the amount of energy that can be obtained from the complete combustion of one cubic foot of butane gas. Understanding the heating value is crucial for various applications, including sizing appliances and calculating fuel needs for heating.

Butane, as a hydrocarbon, possesses a relatively high energy content compared to other gases. It is often used as a fuel in heating systems, cooking, and portable stoves due to this high heating value. In practical applications, knowing the precise heating value allows for better efficiency and planning in both residential and commercial settings, where accurate fuel consumption calculations are essential.

While the other answers may represent heating values of different gases or hydrocarbons, they do not apply to butane specifically. This distinction underscores the importance of knowing the values associated with each type of fuel in the context of gas code regulations and combustion efficiency.
