Cubic foot per minute (CFM) to cup per second (CPS) is a conversion used to measure the flow rate of liquids or gases. CFM represents the volume of a substance flowing through a given area in one minute, typically used in HVAC systems and industrial processes. On the other hand, CPS measures the volume of a substance flowing through a given area in one second, often used in laboratory settings and precision applications. The conversion from CFM to CPS is essential in various fields, including chemistry, engineering, and environmental science, where precise measurements are crucial for experiments, equipment design, and process optimization.
