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

/Hour [gal (US)/h]


Gallon per hour (US) [gal (US)/h] is a unit of volumetric flow rate that measures the volume of liquid passing through a system every hour, using the US liquid gallon as the standard. One US gallon equals approximately 3.785 liters, so gal (US)/h quantifies the amount of fluid flowing in a sixty-minute period. This unit is widely used in industrial processes, water distribution, chemical dosing, and agricultural irrigation in regions where the US gallon is standard. For example, water treatment plants and pumping systems are often rated in gal (US)/h to ensure that the correct volume of water is delivered or treated each hour. In agriculture, irrigation equipment may use gal (US)/h to regulate water supply to crops efficiently. In industrial chemical processes, this unit helps control the flow of liquids for precise reactions or production requirements. Compared to gal (US)/d, gallon per hour provides finer temporal resolution, allowing better monitoring and real-time adjustments. Using gal (US)/h enables engineers, technicians, and agricultural managers to measure, regulate, and optimize fluid flow, ensuring efficiency, reliability, and proper resource management in various applications.
