Cubic Inch/Hour [in³/h]


Cubic inch per hour [in³/h] is a unit of volumetric flow rate that measures the volume of fluid or material passing through a system every hour, based on the cubic inch. One cubic inch equals approximately 16.387 milliliters. When expressed per hour, in³/h is commonly used in laboratory experiments, small-scale industrial processes, and precision fluid handling where very low flow rates need to be monitored accurately. For example, in microfluidic devices or chemical dosing systems, a flow of 100 in³/h allows precise control of reagents or liquids over time. It is also used in specialized lubrication systems, medical fluid delivery, and other applications where small, consistent volumes must be maintained. Compared to in³/day, cubic inch per hour provides finer temporal resolution, enabling operators to monitor and adjust flow in near real time. Using cubic inches per hour allows engineers, scientists, and technicians to measure, regulate, and optimize small-volume flows, ensuring accuracy, safety, and efficiency in laboratory, medical, and industrial applications requiring precise fluid control.


/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.
