Convert milliliter/day [mL/d] to gallon (US)/day [gal (US)/d] 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.

/Day [gal (US)/d]

Gallon per day (US) [gal (US)/d] is a unit of volumetric flow rate that measures the volume of liquid passing through a system over a 24-hour period, using the US liquid gallon as the standard measure. One US gallon equals approximately 3.785 liters, so gal (US)/d quantifies daily fluid usage or delivery in this conventional unit. This unit is commonly used in water supply management, wastewater treatment, agriculture, and industrial applications in countries where the US gallon is standard. For instance, municipal water authorities often express household or commercial water consumption in gal (US)/d to plan distribution, treatment, and storage effectively. In agriculture, irrigation systems may be designed based on daily water requirements of crops, calculated in US gallons per day. In industrial settings, daily consumption or discharge of liquids is monitored in gal (US)/d to optimize processes and ensure efficiency. Compared to gal/h or gal/min, this unit provides a long-term perspective, suitable for planning and monitoring overall daily water or fluid usage. Using gallons per day enables professionals to manage, conserve, and optimize fluid resources, ensuring sustainability, efficiency, and reliable operation across residential, agricultural, and industrial contexts.
