The BTU/hr to HP Calculator is a useful tool for converting British Thermal Units per hour (BTU/hr) into horsepower (HP). This conversion is essential for evaluating engine power, HVAC systems, and various industrial applications.
Formula
The formula for conversion is:
HP = BTU/hr ÷ CF
Where:
- BTU/hr = British Thermal Units per hour
- CF = Conversion Factor (often around 2544.43)
How to Use
- Enter the BTU/hr value.
- Input the conversion factor (if unknown, use 2544.43).
- Click “Calculate” to get the horsepower value.
Example
If a system generates 5000 BTU/hr and the conversion factor is 2544.43:
HP = 5000 ÷ 2544.43
HP ≈ 1.96
FAQs
1. What does BTU/hr measure?
BTU/hr measures the amount of heat energy transferred per hour.

Yes, steam engines use similar power calculations.
14. What industries use this conversion?
HVAC, automotive, industrial machinery, and power generation industries use it.
15. Is there a difference between thermal HP and mechanical HP?
Yes, thermal HP relates to heat energy, while mechanical HP measures force output.
16. Does engine efficiency affect the result?
No, efficiency is not factored into the direct mathematical conversion.
17. Can this calculator be used for air conditioners?
Yes, it helps determine cooling capacities in terms of HP.
18. What if my BTU/hr value is very large?
Larger BTU/hr values will convert to higher horsepower outputs.
19. Can this be used for gas engines?
Yes, gas engines often use BTU/hr to measure energy efficiency.
20. Does this formula work for all energy conversions?
It works specifically for BTU/hr to HP conversions and should not be used for unrelated energy calculations.
