1. What is CFH to CFM Conversion?

CFH (Cubic Feet Per Hour) to CFM (Cubic Feet Per Minute) conversion is a simple calculation used to convert gas flow rates between hourly and minute measurements. This conversion is commonly used in HVAC, gas supply, and industrial 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 the hourly flow rate by 60 gives the equivalent minute flow rate.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is essential for proper system design, equipment sizing, and ensuring adequate gas supply for various applications including heating, ventilation, and industrial processes.

4. Using the Calculator

Tips: Enter the CFH value in cubic feet per hour. The value must be a positive number. The calculator will automatically compute the equivalent CFM value.

5. Frequently Asked Questions (FAQ)

Q1: Why convert CFH to CFM?
A: Different applications and equipment specifications may require flow rates in different time units. CFM is commonly used for minute-based measurements while CFH is used for hourly measurements.

Q2: Is this conversion specific to gases?
A: While this calculator is designed for gas flow rates, the same mathematical conversion applies to any volumetric flow rate measurement.

Q3: What are typical CFH values for residential gas appliances?
A: Residential gas appliances typically range from 20,000 to 200,000 BTU/hour, which corresponds to approximately 20-200 CFH for natural gas.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact since it's based on the fixed relationship between hours and minutes (1 hour = 60 minutes).

Q5: Can I convert CFM back to CFH?
A: Yes, to convert CFM to CFH, simply multiply the CFM value by 60 (CFH = CFM × 60).
