Understanding Cubic feet per hour to Pints per hour Conversion
Cubic feet per hour () and pints per hour () are both units of volume flow rate, meaning they describe how much volume moves or is delivered over time. Cubic feet per hour is commonly used in ventilation, gas flow, and industrial settings, while pints per hour is a smaller-scale unit that may be easier to visualize for liquid dispensing or low-volume transfer.
Converting between these units is useful when comparing systems that use different measurement conventions. It helps express the same flow rate in a unit that better matches the scale of the application.

Cubic feet per hour is generally more convenient for larger flow systems, especially in engineering and building services. Pints per hour is often easier to interpret when dealing with smaller liquid quantities.
Because both units measure volume flow rate, converting between them does not change the physical quantity being described. It only changes the scale and notation used to express the same rate.
In practical use, larger systems are often specified in cubic feet per hour because the numbers remain compact. For very small flows, pints per hour can produce values that are more intuitive for operational monitoring.
The conversion factor is fixed:
That means every value in can be converted directly by multiplication. The inverse factor,

What is Cubic feet per hour?
Cubic feet per hour (CFH) is a unit used to measure the volumetric flow rate. It represents the volume of a substance (gas or liquid) that passes through a specific area per hour, measured in cubic feet. It's a common unit in various fields, especially when dealing with gas and air flow.
Definition of Cubic Feet per Hour
Cubic feet per hour (CFH) is defined as the volume of a substance, measured in cubic feet, that flows past a point in one hour.
How CFH is Formed
CFH is derived from the basic units of volume (cubic feet) and time (hour). It directly expresses how many cubic feet of a substance move within one hour. No special law or constant is specifically tied to the definition of CFH itself. It is a direct measure of flow rate, useful in practical applications.
Calculating Volume Flow Rate
The volume flow rate (Q) in cubic feet per hour can be determined using the following formula:
Where:
- = Volume flow rate (ft³/hour)
- = Cross-sectional area of the flow (ft²)
- = Average velocity of the flow (ft/hour)
Another way to calculate it is:
Where:
- = Volume flow rate (ft³/hour)
- = Volume (ft³)
- = Time (hours)
Real-World Examples of CFH
- Natural Gas Consumption: Home appliances like furnaces, water heaters, and stoves are rated in terms of CFH to indicate their natural gas consumption. A typical furnace might consume 80-120 CFH of natural gas.
- HVAC Systems: Air conditioning and ventilation systems use CFH to measure the airflow rate in ductwork. A residential HVAC system might require airflow rates between 400 and 1600 CFH, depending on the size of the home.
- Compressed Air Systems: Pneumatic tools and equipment in factories use compressed air. The compressor output is often rated in CFH or cubic feet per minute (CFM, which can easily be converted to CFH by multiplying by 60) to indicate the volume of air it can supply.
- Industrial Processes: Many industrial processes, such as chemical manufacturing or food processing, involve controlling the flow rate of liquids or gases. CFH can be used to specify the desired flow rate of a particular fluid. For example, a chemical reactor might require a flow of 50 CFH of nitrogen gas.
- Ventilation Systems: Exhaust fans in bathrooms or kitchens are often rated in CFM (cubic feet per minute), which can be converted to CFH. A typical bathroom exhaust fan might be rated at 50-100 CFM, which equals 3000-6000 CFH.
What is pints per hour?
What is Pints per hour?
Pints per hour (pint/h) is a unit of volumetric flow rate, commonly used to express how much volume of a liquid is moving per unit of time. It is primarily used in the United States and some other countries that still use the imperial system of measurement. Let's break down what that means in simpler terms.
Understanding Pints and Hours
- Pint: A pint is a unit of volume in the imperial and US customary systems. There are different types of pints such as US liquid pint, US dry pint and Imperial pint.
- Hour: An hour is a unit of time.
Combining these, "pints per hour" tells you how many pints of a substance are flowing or being transferred in one hour.
Defining Pints per Hour
Pints per hour (pint/h) is a unit of volumetric flow rate. Volumetric flow rate also know as volume flow rate measure the amount of volume passes through a cross-sectional area per unit of time.
The formula for calculating flow rate is:
Where:
- = Volumetric flow rate
- = Volume (in pints)
- = Time (in hours)
Real-World Applications and Examples
- Beer Dispensing: You might see a beer tap described as dispensing at a rate of, say, 2 pints per hour for a slow, controlled pour or 10 pints per hour for fast dispensing at a busy event.
- IV Fluid Administration: In medical settings, IV fluids might be administered at rates measured in pints per hour, especially when dealing with larger volumes for resuscitation.
- Small Pumps: Small pumps used in aquariums or hydroponics systems might have flow rates specified in pints per hour to indicate how quickly they circulate water or nutrient solutions.
- Condensate Pumps: Condensate pumps that remove water produced by air conditioners or dehumidifiers might have flow rates specified in pints per hour.
- Sprinkler Systems: Very small sprinkler systems or drip irrigation systems could have application rates specified in pints per hour.
Considerations
- Viscosity: The flow rate can be affected by the viscosity of the liquid. More viscous liquids (like honey) will flow slower than less viscous ones (like water).
- Imperial vs. US Pints: Note that there are different pint sizes (Imperial and US), so it's essential to clarify which unit is being used. 1 US liquid pint is equal to 0.832674 Imperial pints.
- Other Flow Rate Units: Other common units for flow rate include gallons per minute (GPM), liters per second (L/s), and cubic meters per hour ().
Interesting Facts
While there isn't a specific law or historical figure directly associated with "pints per hour," the concept of flow rate is fundamental in fluid dynamics. Scientists and engineers like Daniel Bernoulli have contributed significantly to our understanding of fluid behavior, which is closely related to flow rate measurements.
