1. What is CFM to CFH Conversion?

CFM (cubic feet per minute) to CFH (cubic feet per hour) conversion is a simple calculation used to convert flow rates from per-minute to per-hour measurements. This conversion is commonly used in HVAC, ventilation, and airflow calculations.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( CFM \) — Cubic feet per minute
• \( CFH \) — Cubic feet per hour

Explanation: Since there are 60 minutes in an hour, multiplying CFM by 60 converts the flow rate to cubic feet per hour.

3. Importance of CFM to CFH Conversion

Details: Converting CFM to CFH is important for calculating hourly airflow rates, energy consumption calculations, and system capacity planning in ventilation and HVAC applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert CFM to CFH?
A: CFH provides hourly airflow rates which are useful for energy calculations, system capacity planning, and comparing different ventilation systems.

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

Q3: Can this conversion be used for any gas or fluid?
A: Yes, this conversion works for any substance measured in cubic feet per minute, as it's purely a time unit conversion.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact and 100% accurate for converting between these two time-based flow rate units.

Q5: What are typical CFM values in HVAC systems?
A: Residential HVAC systems typically range from 400-2000 CFM, while commercial systems can range from 2000-50,000+ CFM depending on the building size.
