1. What is the BTU to CFH Conversion?

The BTU to CFH conversion calculates the cubic feet per hour (CFH) of gas flow required to produce a specific amount of heat energy measured in British Thermal Units (BTU). This is essential for sizing gas lines and appliances.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ CFH = \frac{BTU}{BTU \text{ per Cubic Foot}} \]

Where:

\( BTU \) — British Thermal Units, a measure of heat energy
\( BTU \text{ per Cubic Foot} \) — The energy content of the gas per cubic foot

Explanation: The formula divides the total BTU requirement by the BTU content per cubic foot of gas to determine the required gas flow rate in cubic feet per hour.

3. Importance of BTU to CFH Conversion

Details: Accurate CFH calculation is crucial for proper sizing of gas piping systems, ensuring appliances receive adequate gas supply while maintaining safe operating pressures.

4. Using the Calculator

Tips: Enter the total BTU requirement and the BTU content per cubic foot of the specific gas being used. Natural gas typically has about 1,000 BTU per cubic foot, but this can vary.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical BTU per cubic foot value for natural gas?
A: Natural gas typically contains approximately 1,000-1,050 BTU per cubic foot, but this can vary by location and gas composition.

Q2: Why is CFH important for gas appliance installation?
A: CFH determines the required gas line size to ensure appliances receive adequate gas flow for proper operation without pressure drops.

Q3: How does altitude affect BTU to CFH calculations?
A: At higher altitudes, gas contains less energy per cubic foot, so BTU per cubic foot values may need adjustment for accurate calculations.

Q4: Can this calculator be used for propane gas?
A: Yes, but propane has a higher BTU content (approximately 2,500 BTU per cubic foot), so use the appropriate value for accurate results.

Q5: What factors can affect gas BTU content?
A: Gas composition, altitude, temperature, and pressure can all affect the actual BTU content per cubic foot of gas.
