Convert milliliter/day [mL/d] to gallon (US)/second Online | Free flow Converter

Milliliter per day (mL/d) is a unit of volumetric flow rate that measures the volume of a liquid passing through a system over a 24-hour period. One milliliter equals one-thousandth of a liter, so mL/d quantifies very small daily fluid volumes, making it ideal for medical, laboratory, and precision dosing applications. In healthcare, mL/d is often used to monitor a patient’s fluid intake or output over a day, ensuring accurate hydration or medication delivery. In laboratory settings, chemical reactions or experiments that require slow, controlled addition of reagents use mL/d to maintain precision and reproducibility. Compared to L/d, this unit provides a much finer scale, suitable for situations where even minor deviations in volume can affect outcomes. It is also used in micro-irrigation systems, specialized industrial processes, and pharmaceutical manufacturing to measure minimal fluid flow accurately. Using milliliters per day allows scientists, engineers, and medical professionals to track, regulate, and optimize very low-volume fluid flows, ensuring consistency, safety, and reliability in sensitive applications where precision is critical.

Second [gal (US)/s]

Gallon per second (US) [gal (US)/s] is a unit of volumetric flow rate that measures the volume of liquid passing through a system every second, using the US liquid gallon as the standard. One US gallon equals approximately 3.785 liters, so gal (US)/s quantifies how many gallons flow each second, making it suitable for applications requiring very high flow rates. This unit is commonly used in hydraulics, large-scale water distribution, industrial processes, and emergency systems where rapid fluid movement must be monitored and controlled accurately. For instance, in water supply networks or dam releases, gal (US)/s helps engineers design pipelines, pumping stations, and valves to deliver large volumes of water efficiently. In industrial manufacturing, it regulates the flow of liquids in processes like cooling, chemical mixing, or fuel transfer, ensuring smooth and safe operation. Compared to gal/min or gal/h, gallon per second provides real-time measurement and control, enabling immediate response to changes in flow demand. Using gal (US)/s allows engineers, technicians, and managers to measure, manage, and optimize high-volume fluid flow, ensuring efficiency, safety, and reliable operation in critical municipal and industrial applications.
