1. What is CFH to CFM Conversion?

CFH (cubic feet per hour) to CFM (cubic feet per minute) conversion is used to convert airflow rates between different time units, particularly useful for bathroom ventilation calculations.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

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

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

3. Importance of CFM Calculation

Details: Proper CFM calculation is essential for designing effective bathroom ventilation systems to remove moisture, odors, and maintain air quality.

4. Using the Calculator

Tips: Enter CFH value in cubic feet per hour. The value must be greater than zero for accurate conversion.

5. Frequently Asked Questions (FAQ)

Q1: Why convert CFH to CFM for bathrooms?
A: Bathroom ventilation requirements are typically specified in CFM, making this conversion necessary when equipment specifications are in CFH.

Q2: What is a typical CFM requirement for bathrooms?
A: Most building codes require 50 CFM for bathrooms with showers and 20 CFM for bathrooms without showers.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact since it's a simple division by 60 (minutes per hour).

Q4: Can this conversion be used for other applications?
A: Yes, this conversion can be used for any airflow rate conversion between hourly and minute units.

Q5: What if I need to convert CFM back to CFH?
A: Simply multiply the CFM value by 60 to get CFH (CFH = CFM × 60).
