Hour [mL/h]


Milliliter per hour (mL/h) is a unit of volumetric flow rate that measures the volume of a liquid passing through a system every hour. One milliliter equals one-thousandth of a liter, so mL/h quantifies small fluid volumes with higher temporal resolution, making it ideal for medical, laboratory, and industrial applications. In healthcare, mL/h is commonly used to regulate intravenous fluid administration, ensuring patients receive the correct amount of medication or nutrients per hour. In chemical and biological laboratories, precise dispensing of reagents in mL/h ensures accurate experiments and reactions. Compared to mL/d, this unit allows for more frequent monitoring and finer control, which is crucial for processes that require continuous or incremental dosing. It is also used in pharmaceutical manufacturing, microfluidics, and analytical instruments where controlled fluid flow is essential. Using milliliters per hour enables professionals to measure, manage, and optimize small-scale fluid delivery, maintaining accuracy, safety, and consistency in critical applications where even minor variations can significantly impact results and outcomes.


/Day [bbl (US)/d]


Barrel per day (US) [bbl (US)/d] is a unit of volumetric flow rate widely used in the oil and gas industry to measure the daily production, transport, or consumption of crude oil and petroleum products. One US barrel equals approximately 159 liters, so bbl (US)/d quantifies how many barrels of oil flow or are produced each day. This unit is commonly used by oil companies, refineries, and energy analysts to monitor production rates, assess pipeline capacities, and plan storage and distribution. For example, an oil well producing 10,000 bbl (US)/d delivers 10,000 barrels of crude oil per day, allowing planners to estimate revenue, manage supply chains, and schedule transportation. It is also used to compare output across fields, track consumption trends, and optimize refinery operations. Compared to smaller units like barrels per hour, bbl (US)/d provides a long-term perspective, making it suitable for strategic planning, reporting, and operational analysis in the petroleum sector. Using barrel per day allows professionals to monitor, manage, and optimize oil production and flow, ensuring efficiency, safety, and effective resource allocation in large-scale energy operations.
