Understanding Cubic feet per hour to Tablespoons per second Conversion
Cubic feet per hour () and tablespoons per second () are both units of volume flow rate, which describes how much volume moves through a system over time. Cubic feet per hour is more common in ventilation, gas flow, and industrial settings, while tablespoons per second is a much smaller-scale unit that can be useful for household, kitchen, laboratory, or dosing comparisons.
Converting between these units helps express the same flow in a scale that better matches the application. A large airflow measured in cubic feet per hour may be easier to compare with small dispensing or liquid-transfer rates when converted into tablespoons per second.

Interesting Facts
- The cubic foot is a customary unit based on the foot, which is defined exactly as meter in the international system. This makes cubic-foot-based measurements common in the United States for airflow, natural gas, and building-related volume calculations.

- The tablespoon is a traditional cooking and household volume unit widely used in the United States, and it appears in common measurement references alongside teaspoons, cups, and fluid ounces. Source: Wikipedia - Tablespoon
A conversion such as to bridges a large-scale hourly unit and a much smaller per-second unit. This can be especially useful when comparing engineering data with dosing, mixing, culinary, or laboratory-style measurements.
Because the two units differ greatly in scale, the converted number in tablespoons per second often appears much larger than the original number in cubic feet per hour. That does not indicate a change in actual flow, only a change in how the same rate is expressed.
Using the verified conversion factor ensures consistency:
And for reverse checks:
These relationships are useful in specification sheets, educational examples, and cross-system measurement comparisons where both customary volumetric and small dispensing units may appear.

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 Tablespoons per second?
Tablespoons per second (tbsp/s) is a unit measuring volume flow rate – the amount of volume that passes through a given area per unit of time. This particular unit is commonly used to express small or moderate flow rates, especially in cooking, baking, and pharmaceutical contexts.
Understanding Tablespoons
-
Definition: A tablespoon (tbsp) is a unit of volume in the imperial and US customary systems.
-
Equivalence:
- 1 tablespoon (US) = approximately 14.8 milliliters (mL)
- 1 tablespoon (UK) = approximately 17.7 milliliters (mL)
- 1 tablespoon = 3 teaspoons
-
Usage: Tablespoons are frequently used in recipes for measuring ingredients like liquids (oil, sauces) and dry goods (spices, sugar).
Deciphering "per Second"
The "per second" part of the unit indicates the time frame over which the volume of one or more tablespoons is measured.
- Meaning: How many tablespoons flow past a certain point in one second.
- Implication: A higher value (e.g., 5 tbsp/s) indicates a faster flow rate than a lower value (e.g., 1 tbsp/s).
Tablespoons per Second Formula
Volume flow rate () is generally defined as:
Where:
- = Volume flow rate
- = Volume (in this case, measured in tablespoons)
- = Time (in seconds)
To calculate average flow rate, measure the volume moved in time and divide.
Real-World Examples and Applications
While "tablespoons per second" might not be a standard industrial unit, here are some contexts where understanding this flow rate is helpful:
- Medicine Dispensing: Some medical devices or automated systems might dispense liquid medication at a controlled rate, potentially expressible in tbsp/s for small volumes. For example, a dispensing system might release 0.1 tbsp/s of a particular syrup.
- Small-Scale Chemical Reactions: In chemistry, when conducting experiments that require specific volumes of liquids to be added slowly, flow rates can be calculated and approximated.
- Novelty Water Fountains/Features: Imagine a decorative water fountain designed to release water in small bursts. These bursts could be designed and measured in tbsp/s.
- Pumps: Dosing pumps often have low flow rates that can sometimes be easier to visualize in tbsp/s.
- Baking: Measuring vanilla extract dispensed from a dropper would be a good example.
