Conversion Formula:
| From: | To: |
The boiler horsepower to BTU per hour conversion is a standard calculation used in heating and power generation industries to convert boiler horsepower units to British thermal units per hour, which measures heat output capacity.
The calculator uses the conversion formula:
Where:
Explanation: This conversion is based on the standard definition where one boiler horsepower equals the energy needed to evaporate 34.5 pounds of water per hour at 212°F, which equals 33475 BTU per hour.
Details: Accurate conversion between boiler horsepower and BTU/hr is essential for proper boiler sizing, efficiency calculations, and comparing heating capacities across different systems and manufacturers.
Tips: Enter the boiler horsepower value. The value must be a positive number greater than zero. The calculator will automatically compute the equivalent BTU per hour.
Q1: What is the difference between boiler HP and mechanical HP?
A: Boiler horsepower is a unit of measurement for boiler power output (33475 BTU/hr), while mechanical horsepower (745.7 watts) measures mechanical power. They are different units for different applications.
Q2: Why is the conversion factor 33475?
A: This factor comes from the historical definition where one boiler horsepower was defined as the energy required to evaporate 34.5 pounds of water per hour at 212°F, which equals 33475 BTU per hour.
Q3: Can this calculator be used for all types of boilers?
A: Yes, the conversion is standard and applies to all boiler types when converting between boiler horsepower and BTU per hour measurements.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the standard definition, so it provides precise results for calculation purposes.
Q5: Where is this conversion typically used?
A: This conversion is commonly used in HVAC industry, power plant operations, industrial heating systems, and boiler specification sheets for comparing capacity ratings.
