Centimeter/Second [cm³/s]


Cubic centimeter per second (cm³/s) is a unit of volumetric flow rate that measures the volume of a fluid—liquid or gas—passing through a system every second. One cubic centimeter represents a cube with sides of one centimeter, so cm³/s indicates how many such tiny volumes flow each second. This unit is widely used in laboratory experiments, microfluidics, medical devices, and precision engineering where rapid yet small-scale fluid flows need to be monitored and controlled. For example, in medical applications, devices such as infusion pumps or respiratory equipment often rely on cm³/s measurements to ensure exact fluid or gas delivery. In microfluidics and chemical laboratories, reagents or solvents are dispensed at rates specified in cm³/s to maintain reaction accuracy and consistency. Compared to cm³/min, this unit allows for finer temporal resolution, enabling real-time monitoring and precise adjustment of flow rates. Using cubic centimeters per second, scientists, engineers, and technicians can track, regulate, and optimize fluid movement with high accuracy, ensuring efficiency, safety, and reliable performance in both experimental and industrial applications where even small variations in flow can significantly affect outcomes.


/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.
