Energy to Flow Converter
How to Use the BTU to m3/hr Calculator
- Enter BTU Value: Input the energy value in BTU (British Thermal Units).
- Select Gas Type: Choose the gas type such as natural gas or LPG. Different gases have different energy contents.
- Apply Conversion Factor: The calculator uses a standard conversion factor based on gas energy content.
- Click Calculate: The tool converts BTU into cubic meters per hour (m3/hr).
- Read the Result: The output shows the required gas flow rate in m3/hr.
Tip: Always verify the gas calorific value for accurate results.
BTU to m3/hr Conversion Guide
To convert BTU to m3/hr, use this formula:
For natural gas, the standard approximation is:
Simplified formula for natural gas:
Note: Always adjust based on actual gas calorific value if available.
Example Calculation
Convert 100,000 BTU to m3/hr for natural gas:
1. Write the formula: m3/hr = 100,000 ÷ 35,315
2. Perform division: m3/hr ≈ 2.8316
3. Final Answer: 100,000 BTU ≈ 2.83 m3/hr

Frequently Asked Questions (FAQs)
A BTU to m3/hr calculator converts energy (BTU) into gas flow rate (cubic meters per hour). It helps in gas system design and sizing.
You need this conversion to determine gas consumption for burners, boilers, and HVAC systems.
The average value is 1 m3 ≈ 35,315 BTU. This value may vary based on gas composition.
Yes. Different gases have different calorific values. Always use the correct value for accurate results.
Yes, but you must use the correct LPG calorific value instead of natural gas.
No. It is an approximation unless you use precise gas composition data.
HVAC, oil and gas, manufacturing, and energy sectors commonly use this conversion.
Use the exact calorific value provided by your gas supplier.
Yes. It works for both small and large-scale industrial calculations.
Yes. Multiply m3/hr by the calorific value to convert back to BTU.
