CFH to CFM Conversion Formula:
| From: | To: |
CFH (Cubic Feet Per Hour) to CFM (Cubic Feet Per Minute) conversion is essential in air conditioning and ventilation systems to convert hourly airflow rates to minute-based measurements, which are more commonly used in system specifications and calculations.
The calculator uses the simple conversion formula:
Where:
Explanation: Since there are 60 minutes in an hour, dividing CFH by 60 converts the measurement to a per-minute basis.
Details: CFM measurements are crucial for proper air conditioning system design, ensuring adequate airflow for cooling/heating capacity, maintaining indoor air quality, and optimizing energy efficiency in HVAC systems.
Tips: Enter CFH value in cubic feet per hour. The value must be greater than 0. The calculator will automatically convert it to CFM (cubic feet per minute).
Q1: Why convert CFH to CFM in AC systems?
A: CFM is the standard measurement used in air conditioning specifications, duct design, and fan performance ratings, making conversions necessary when working with hourly data.
Q2: What is a typical CFM range for residential AC systems?
A: Residential systems typically range from 400-2000 CFM, depending on the size of the space and cooling capacity requirements.
Q3: How does CFM relate to tonnage in AC units?
A: Generally, 400 CFM per ton of cooling is standard, though this can vary based on specific system design and climate conditions.
Q4: Can this conversion be used for other gases besides air?
A: Yes, the conversion is valid for any gas or fluid volume measurement, as it's purely a time unit conversion (hours to minutes).
Q5: What's the difference between CFM and CMH?
A: CFM is Cubic Feet Per Minute (imperial), while CMH is Cubic Meters Per Hour (metric). They measure the same concept but use different volume and time units.
