BTU to HP Conversion Formula:
| From: | To: |
The BTU to horsepower conversion is used to convert British thermal units per hour (BTU/hr) to mechanical horsepower (HP). This conversion is commonly used in HVAC systems, engine specifications, and power calculations where different units of power measurement need to be compared or converted.
The calculator uses the conversion formula:
Where:
Explanation: One mechanical horsepower is equivalent to approximately 2545 BTU per hour, making this conversion factor standard for power unit conversions.
Details: Accurate power unit conversion is essential for engineers, technicians, and professionals working with heating systems, air conditioning units, engines, and industrial equipment where different measurement systems are used.
Tips: Enter the BTU per hour value in the input field. The value must be greater than zero. The calculator will automatically compute the equivalent horsepower.
Q1: What is the exact conversion factor?
A: The standard conversion factor is 1 HP = 2544.43 BTU/hr, but 2545 is commonly used for practical calculations and is sufficiently accurate for most applications.
Q2: Is this mechanical or electrical horsepower?
A: This conversion uses mechanical horsepower (also known as imperial horsepower). Electrical horsepower conversion uses a slightly different factor (1 HP = 2546.14 BTU/hr).
Q3: Where is this conversion commonly used?
A: This conversion is frequently used in HVAC industry for comparing cooling capacity (BTU/hr) with motor power (HP), and in automotive and industrial applications.
Q4: Can I convert horsepower back to BTU/hr?
A: Yes, to convert horsepower to BTU/hr, multiply the horsepower value by 2545 (BTU/hr = HP × 2545).
Q5: What's the difference between BTU and BTU/hr?
A: BTU is a unit of energy, while BTU/hr is a unit of power (energy per unit time). This calculator specifically converts BTU per hour to horsepower.
