Cubic Foot/Minute [ft³/min]


Cubic foot per minute [ft³/min] is a unit of volumetric flow rate that measures the volume of fluid or material passing through a system every minute, based on the cubic foot. One cubic foot equals approximately 28.3168 liters. Expressed per minute, ft³/min is widely used in HVAC systems, industrial processes, water distribution, and pneumatic systems where real-time monitoring of moderate to high flow rates is essential. For example, in ventilation systems, an airflow of 500 ft³/min ensures proper circulation and air quality in commercial or industrial buildings. In industrial applications, ft³/min is used to monitor liquid or gas flow through pipelines, ensuring consistent production and process efficiency. It is also applied in water treatment, chemical dosing, and small-scale material handling. Compared to ft³/h, cubic foot per minute provides higher temporal resolution, allowing operators to make immediate adjustments and maintain precise flow control. Using cubic feet per minute enables engineers, technicians, and facility managers to measure, monitor, and optimize volumetric flow, ensuring efficiency, safety, and reliability in industrial, municipal, and building systems.


/Second [L/s]


Liter per second (L/s) is a unit of volumetric flow rate that measures the volume of liquid passing through a system every second. One liter equals 1,000 cubic centimeters, so L/s quantifies how many liters flow per second, making it ideal for applications requiring rapid fluid movement. This unit is widely used in hydraulics, industrial processes, water supply systems, and large-scale chemical operations where high flow rates must be monitored and controlled precisely. For instance, in water distribution networks, L/s helps engineers design pipelines and pumping stations to deliver sufficient water to meet demand during peak usage. In industrial manufacturing, it regulates the flow of liquids in processes like cooling, chemical mixing, or fuel supply, ensuring efficiency and safety. Compared to L/min or L/h, liter per second provides a much finer temporal resolution, enabling real-time monitoring and control of high-volume flows. Using L/s allows professionals to measure, manage, and optimize fluid transport effectively, ensuring operational efficiency, system reliability, and accurate delivery in both industrial and municipal contexts where rapid and precise fluid movement is essential.
