/Second [mL/s]


Milliliter per second (mL/s) is a unit of volumetric flow rate that measures the volume of a liquid passing through a system every second. One milliliter equals one-thousandth of a liter, so mL/s quantifies very small fluid volumes with high temporal resolution, making it ideal for medical, laboratory, and microfluidic applications where precise and rapid flow control is essential. In healthcare, mL/s is used in devices such as infusion pumps or ventilators to deliver fluids or gases accurately and safely. In chemical and biological laboratories, it enables precise reagent dispensing in experiments and reactions requiring strict control over flow rates. Compared to mL/min or mL/h, milliliter per second provides real-time measurement, allowing immediate adjustments and monitoring of processes. This unit is also applied in pharmaceutical manufacturing, analytical instruments, and micro-engineering systems where tiny variations in flow can significantly impact results. Using milliliters per second allows scientists, engineers, and medical professionals to track, manage, and optimize fluid flow with extreme precision, ensuring consistency, efficiency, and safety in sensitive applications where every fraction of a milliliter per second matters.


t/Year [ac·ft/y]


Acre-foot per year [ac·ft/y] is a unit of volumetric flow rate commonly used in hydrology, water resource management, and irrigation planning. One acre-foot represents the volume of water required to cover one acre of land to a depth of one foot, which is approximately 1,233 cubic meters or 325,851 gallons. When expressed per year, ac·ft/y quantifies the total water volume delivered, used, or available over a 12-month period. This unit is particularly useful for managing large-scale water supplies, such as reservoirs, rivers, or agricultural irrigation systems, providing a standardized measure to estimate annual water availability and consumption. For example, an irrigation system supplying 500 ac·ft/y delivers enough water to cover 500 acres to a depth of one foot over a year. It is also used to plan municipal water supply, allocate water rights, and forecast long-term resource needs. Compared to daily or monthly flow units, acre-foot per year gives a macro-level perspective, suitable for long-term planning, resource management, and sustainability assessments. Using ac·ft/y enables engineers, hydrologists, and policymakers to monitor, manage, and optimize water resources, ensuring efficient allocation and conservation for agricultural, municipal, and industrial use.
