BTU/h = CFH × 1030 (for propane)
| From: | To: |
The CFH to BTU conversion calculates the British Thermal Units per hour from Cubic Feet per Hour of gas flow. For propane, this conversion uses a specific energy content factor of 1030 BTU per cubic foot.
The calculator uses the propane conversion formula:
Where:
Explanation: This formula converts the volumetric flow rate of propane gas into its equivalent energy output per hour, based on the standard energy content of propane.
Details: Accurate BTU calculation is essential for sizing heating equipment, determining fuel consumption rates, calculating heating capacity requirements, and ensuring proper system design for propane-powered appliances.
Tips: Enter CFH value in cubic feet per hour. The value must be positive and valid. The calculator will automatically compute the BTU per hour output for propane gas.
Q1: Why is 1030 used for propane conversion?
A: 1030 BTU per cubic foot is the standard energy content value for propane gas at standard temperature and pressure conditions.
Q2: Does this conversion work for natural gas?
A: No, natural gas has a different energy content (approximately 1000-1100 BTU per cubic foot). Use the appropriate conversion factor for natural gas calculations.
Q3: What are typical CFH values for propane appliances?
A: Typical values range from 10-400 CFH depending on the appliance size, with furnaces using 50-200 CFH and water heaters using 20-100 CFH.
Q4: How accurate is this conversion?
A: The conversion is accurate for standard conditions. Actual values may vary slightly based on gas purity, temperature, and pressure conditions.
Q5: Can this be used for system sizing?
A: Yes, this calculation is commonly used for sizing propane heating systems, determining pipe sizes, and calculating fuel storage requirements.
