liter/second [L/s] Unit Converter

Definition of liter/second [L/s] unit

The liter per second (L/s) is a derived SI-compatible unit of volumetric flow rate, representing the volume of one liter passing a given point or entering a system every second. It equals 0.001 cubic meters per second.

History of liter/second [L/s] unit

The liter originated from the French metric system, established during the Revolution and formally defined in 1795 as a cubic decimeter. Although the unit’s name and exact reference definitions evolved, the liter became widely accepted for measuring liquid and gas volumes. Expressing flow in liters per second developed naturally with modern hydraulics, pumps, and engineering. Internationally, the cubic meter per second is the SI unit, while liter per second remains a practical decimal subdivision, especially in technical specifications, laboratory work, and water-management standards.

Applications of liter/second [L/s] unit

Liter per second is commonly used to describe water flow in pipes, filtration systems, wells, irrigation equipment, and wastewater plants. It also appears in laboratory instruments, medical devices, and industrial process controls. For example, a pump rated at 5 L/s delivers five liters of fluid each second under specified operating conditions.
