Imperial Horsepower (hp) to British Thermal Unit per Second (Btu/s) Conversion
Imperial horsepower to British thermal unit per second conversion is an important calculation in HVAC, refrigeration equipment and industrial heating systems. This tool provides precise hp to Btu/s power unit conversion, helping engineers with equipment selection, system design and power matching calculations. Whether you are designing HVAC systems, selecting refrigeration equipment or calculating industrial heating power, this tool provides accurate conversion results and professional engineering guidance.
Conversion Formula
The conversion between imperial horsepower (hp) and British thermal unit per second (Btu/s) is based on their energy definitions:
Basic Formula:
- 1 hp = 745.7 watts
- 1 Btu/s = 1,055.06 watts
- 1 hp = 0.70707 Btu/s
- 1 Btu/s = 1.41427 hp
Conversion Formulas:
- hp to Btu/s: Btu/s = hp × 0.70707
- Btu/s to hp: hp = Btu/s × 1.41427
Application Examples
HVAC Systems
- Central Air Conditioning: 5-ton AC unit requires 17.5 hp (12.37 Btu/s) compressor
- Heat Pumps: Residential heat pump 3 hp motor equals 2.12 Btu/s heating capacity
- Ventilation Fans: Industrial exhaust fan 2 hp motor equals 1.41 Btu/s power consumption
Refrigeration Equipment
- Commercial Refrigerators: Walk-in cooler compressor 7.5 hp equals 5.30 Btu/s
- Ice Machines: Large ice machine 10 hp compressor equals 7.07 Btu/s
- Cold Storage: Warehouse refrigeration system 50 hp equals 35.35 Btu/s
Industrial Heating
- Boiler Systems: Industrial boiler 100 hp equals 70.7 Btu/s thermal output
- Process Heating: Manufacturing process heater 25 hp equals 17.68 Btu/s
- Steam Generation: Steam boiler 200 hp equals 141.4 Btu/s capacity
Usage Recommendations
- HVAC Design: Use Btu/s for thermal calculations, hp for motor specifications
- Equipment Selection: Consider both mechanical power (hp) and thermal capacity (Btu/s)
- Energy Efficiency: Compare equipment using consistent units for accurate analysis
- System Sizing: Account for efficiency losses when converting between units
- Cost Analysis: Use appropriate units for energy consumption calculations
