Natural Gas Heat Conversion Formula:
| From: | To: |
The CFH to BTU conversion calculates the heat output of natural gas based on its flow rate. CFH (Cubic Feet per Hour) measures gas volume flow, while BTU/h (British Thermal Units per hour) measures heat energy output.
The calculator uses the natural gas heat conversion formula:
Where:
Explanation: The conversion factor of 1025 BTU per cubic foot represents the typical heat content of natural gas, though this can vary slightly depending on gas composition and local standards.
Details: Accurate BTU calculation is essential for sizing heating equipment, determining fuel consumption, calculating heating costs, and ensuring proper system performance for residential and commercial applications.
Tips: Enter the gas flow rate in cubic feet per hour (CFH). The value must be positive and greater than zero. The calculator will instantly compute the corresponding heat output in BTU per hour.
Q1: What is the typical BTU content of natural gas?
A: Natural gas typically contains approximately 1025-1030 BTU per cubic foot, though this can vary by region and gas composition.
Q2: How accurate is this conversion factor?
A: The 1025 BTU/cf factor is a standard average. For precise calculations, consult your local gas utility for the exact heat content in your area.
Q3: Can this calculator be used for propane or other gases?
A: No, this calculator is specifically for natural gas. Propane has a different energy content (approximately 2500 BTU/cf) and requires a different conversion factor.
Q4: What applications use CFH to BTU conversion?
A: This conversion is used for furnace sizing, boiler capacity calculations, gas appliance specifications, and energy consumption analysis.
Q5: How does altitude affect the calculation?
A: At higher altitudes, air density decreases, which may affect combustion efficiency. For high-altitude applications, consult manufacturer specifications for altitude correction factors.
