Conversion Formula:
| From: | To: |
The horsepower to BTU per hour conversion is used to convert mechanical power (horsepower) to thermal power (BTU per hour). This conversion is essential in HVAC systems, engine performance analysis, and energy calculations where both mechanical and thermal power measurements are involved.
The calculator uses the conversion formula:
Where:
Explanation: One horsepower is equivalent to 2545 BTU per hour, based on the mechanical equivalent of heat where 1 HP = 2545 BTU/h.
Details: Accurate power conversion between horsepower and BTU/h is crucial for system design, energy efficiency calculations, equipment sizing, and performance analysis in mechanical and thermal engineering applications.
Tips: Enter horsepower value in the input field. The value must be positive and valid. The calculator will automatically compute the equivalent BTU per hour.
Q1: Why is the conversion factor 2545?
A: The factor 2545 comes from the mechanical equivalent of heat where 1 horsepower = 2544.43 BTU/h, typically rounded to 2545 for practical calculations.
Q2: What is the difference between HP and BTU/h?
A: Horsepower measures mechanical power while BTU/h measures thermal power. This conversion allows comparison between mechanical work and heat energy.
Q3: Where is this conversion commonly used?
A: Commonly used in HVAC system design, engine performance analysis, industrial heating systems, and energy efficiency calculations.
Q4: Is this conversion exact?
A: The conversion uses a standard factor of 2545 BTU/h per HP, which is widely accepted in engineering practice, though slight variations may exist in specific applications.
Q5: Can I convert BTU/h back to HP?
A: Yes, to convert BTU/h to HP, divide the BTU/h value by 2545 using the formula: HP = BTU/h ÷ 2545.
