1. What is CFH to CFM Conversion?

CFH (cubic feet per hour) and CFM (cubic feet per minute) are both units of volumetric flow rate used to measure the movement of gases or liquids. Converting between these units is essential in various engineering and HVAC applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( CFM \) — Cubic feet per minute (ft³/min)
• \( CFH \) — Cubic feet per hour (ft³/h)

Explanation: Since there are 60 minutes in an hour, dividing CFH by 60 converts the flow rate from per hour to per minute.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for system design, equipment sizing, and performance calculations in HVAC, plumbing, and industrial processes where different time units may be specified.

4. Using the Calculator

Tips: Enter the CFH value in the input field. The value must be a positive number. The calculator will automatically compute the equivalent CFM value.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between CFH and CFM?
A: Different applications and equipment specifications may use different time units for flow rates, making conversion necessary for accurate system design and comparison.

Q2: Is the conversion factor always 60?
A: Yes, since there are exactly 60 minutes in one hour, the conversion factor from CFH to CFM is always 1/60.

Q3: Can this conversion be used for any fluid?
A: Yes, this conversion applies to both liquids and gases, as it's purely a time unit conversion, not dependent on the fluid properties.

Q4: How precise is this conversion?
A: The conversion is mathematically exact, as it's based on the fixed relationship between hours and minutes.

Q5: Are there other common flow rate units?
A: Yes, other common units include liters per minute (LPM), gallons per minute (GPM), and cubic meters per hour (m³/h), which may require different conversion factors.
