Detailed Steps to Convert BTU/hr to kW
Step-by-Step Conversion Process
Converting BTU per hour to kilowatts involves a simple multiplication or division using the fixed factor of 0.000293071. Follow these steps for accurate results:
Step 1: Identify the BTU/hr Measurement
Determine the number of BTU per hour you need to convert (e.g., 10,000 BTU/hr). Ensure you’re working with BTU/hr, not BTU.
Step 2: Know the Conversion Factor
The fixed conversion rate is 1 BTU/hr = 0.000293071 kW, or 1 kW ≈ 3,412.14 BTU/hr.
Step 3: Apply the Conversion Formula
Use the formula: kW = BTU/hr × 0.000293071. For 10,000 BTU/hr: 10,000 × 0.000293071 ≈ 2.93 kW.
Step 4: Handle Decimals for Precision
For partial BTU/hr (e.g., 12,500 BTU/hr), multiply: 12,500 × 0.000293071 ≈ 3.66 kW. Use a calculator for accuracy with complex decimals.
Step 5: Verify or Convert kW to BTU/hr
Check by dividing kW by 0.000293071. For 2.93 kW: 2.93 ÷ 0.000293071 ≈ 10,000 BTU/hr. For reverse conversions: BTU/hr = kW × 3,412.14. Example: 5 kW × 3,412.14 ≈ 17,060.7 BTU/hr.
Quick Tips for Success
- Use a calculator for precise decimal conversions.
- Round to two decimal places for practical use (e.g., 2.93071 kW ≈ 2.93 kW).
- Use our converter for quick results without manual calculations.
- Confirm you’re using BTU/hr, not BTU or other units like horsepower.
