How is the demand for gas typically expressed?

The demand for gas is typically expressed in cubic feet per hour because this unit measures the volumetric flow of gas in relation to time, which is crucial for assessing how much gas is needed or consumed in a given period for various applications, such as heating or powering equipment. This measurement allows plumbers and gas service professionals to size gas lines and appliances accurately to ensure safe and efficient gas delivery.

While BTU per minute represents energy content and could be relevant in certain contexts, it does not standardize the volumetric flow in a way that is as commonly utilized in plumbing practice. Pounds per hour and liters per hour do not align with standard practices in the gas industry for measuring demand, as gas demand is conventionally quantified in volumetric terms rather than weight or liters directly. Thus, cubic feet per hour is the most appropriate and widely accepted metric for expressing gas demand.
