The unit of measurement that is utilized to determine airflow rates is cubic feet per minute (cfm). This measurement specifically quantifies the volume of air that flows through a given space over the course of one minute, which is crucial in fields such as HVAC (heating, ventilation, and air conditioning) to evaluate system performance and ensure adequate indoor air quality.

In contrast, pascals are used to measure pressure, which is important for understanding the force exerted by air but not the volume. Gallons per minute (gpm) pertains to the flow rate of fluids, typically water, rather than air. Lastly, decibels (dB) measure the intensity of sound, which does not relate to airflow rate at all. Therefore, the focus on cfm effectively addresses the measurement of airflow used in various applications related to environmental control and sustainability practices.
