1. What is CFH to BTU/h Conversion?

The CFH to BTU/h conversion calculates the energy content of natural gas flow. CFH (Cubic Feet per Hour) measures the volume flow rate of natural gas, while BTU/h (British Thermal Units per hour) measures the heating power or energy output.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

\[ BTU/h = CFH \times 1000 \]

Where:

\( BTU/h \) — British Thermal Units per hour (energy output)
\( CFH \) — Cubic Feet per Hour (gas flow rate)
\( 1000 \) — Conversion factor (approximate BTU content per cubic foot of natural gas)

Explanation: This conversion assumes standard natural gas with approximately 1000 BTU per cubic foot. Actual values may vary slightly depending on gas composition.

3. Importance of CFH to BTU/h Conversion

Details: This conversion is essential for sizing heating equipment, calculating fuel consumption, determining heating capacity requirements, and energy management in residential, commercial, and industrial applications.

4. Using the Calculator

Tips: Enter the CFH value (cubic feet per hour of natural gas flow). The value must be positive. The calculator will automatically compute the corresponding BTU per hour output.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 1000?
A: Standard natural gas typically contains approximately 1000 BTU per cubic foot, though this can vary from 950 to 1150 BTU/cf depending on the gas composition and local standards.

Q2: What is CFH used for?
A: CFH measures the volume flow rate of natural gas and is commonly used for sizing gas pipes, meters, and regulating equipment capacity.

Q3: What is BTU/h used for?
A: BTU/h measures heating capacity and is used to specify furnace sizes, boiler capacities, and other heating equipment ratings.

Q4: Is this conversion accurate for all natural gas?
A: While 1000 BTU/cf is a standard average, actual energy content varies. For precise calculations, consult your local gas utility for the exact BTU content.

Q5: Can this calculator be used for propane or other gases?
A: No, this calculator is specifically for natural gas. Propane has a different energy density (approximately 2500 BTU/cf) and requires a different conversion factor.
