Cubic Foot Per Minute (CFM) and Litre Per Second (LPS) are two distinct units used to measure airflow and fluid flow rates in various applications. CFM is commonly employed in the United States to express the volume of air or gas flowing through a system per minute, often used in ventilation systems, HVAC, and industrial processes. On the other hand, LPS is widely used in the International System of Units (SI) to measure the flow rate of liquids or gases in litres per second. The conversion from CFM to LPS is essential in ensuring accurate measurements and calculations across different industries, particularly in scientific research, engineering, and manufacturing. By understanding this conversion, professionals can effectively compare and contrast flow rates, optimize system performance, and make informed decisions in their respective fields.
