How can the input rating of an appliance be converted into cubic foot of gas?

To convert the input rating of an appliance, expressed in BTUs (British Thermal Units), into cubic feet of gas, the process involves understanding the relationship between energy in BTUs and the volume of gas required to produce that energy. Specifically, each type of gas has a specific heat value, which indicates the number of BTUs produced per cubic foot of gas.

By dividing the BTU input by the heat value of the gas, you calculate the total volume of gas needed to produce that amount of energy. Essentially, this division allows you to determine how many cubic feet of gas are necessary to achieve the energy output indicated by the BTU input.

For example, if an appliance has a BTU input of 100,000 BTUs and the gas being used has a heat value of 1,000 BTUs per cubic foot, dividing 100,000 by 1,000 results in 100 cubic feet of gas needed. This method effectively converts the energy requirement into a volumetric measure, allowing for practical applications in heating systems and gas supply calculations.

Other options do not correctly reflect the proper mathematical relationship needed for this conversion, as one involves unnecessary addition or subtraction of values, while another suggests an incorrect multiplication, which would not yield the
