In which unit is volume typically measured for airflow?

The measurement of airflow is typically expressed in terms of volume per time, and using cubic feet per hour is a standard practice in many HVAC (heating, ventilation, and air conditioning) applications. This unit provides a practical way to express airflow quantities, as it allows for an understanding of how much air is being moved through a system over a specific period.

Cubic feet per hour aligns well with the customary measurements used in buildings and populations where this unit can easily relate to other practical and operational concerns in HVAC and ventilation systems. The choice reflects a balance between precision needed for engineering calculations and comprehensibility for practical applications.

Other options, while also valid units for measuring volume, are less common in the context of airflow. For instance, cubic centimeters per minute may be used in very small-scale applications or laboratory settings, cubic liters per second offers a more metric approach suitable for certain scientific measurements, and cubic meters per day is often more applicable for larger scales rather than the flow measurements typically required in standard airflow applications.
