Power Converter

Power conversion is essential in automotive, electrical engineering, HVAC, and mechanical systems. Understanding different power units helps in comparing engine specifications, electrical consumption, and heating/cooling capacities.

Common Power Units

• Watt (W): SI unit of power (1 W = 1 J/s)
• Kilowatt (kW): 1,000 watts
• Horsepower (HP): Mechanical power unit (745.7 watts)
• BTU per Hour: British Thermal Units per hour (HVAC standard)

Conversion Factors

• 1 horsepower (HP) = 745.7 watts = 0.7457 kW
• 1 kilowatt (kW) = 1,000 watts = 1.341 HP
• 1 watt = 3.41214 BTU/hr
• 1 BTU/hr = 0.293071 watts
• 1 HP = 2,544.43 BTU/hr

Applications

• Automotive: Engine power (HP), electric vehicle motors (kW)
• Electrical: Appliance consumption, electrical systems (W, kW)
• HVAC: Air conditioner and heater capacity (BTU/hr, tons)
• Industrial: Motor specifications, machinery power ratings
• Renewable Energy: Solar panel output, wind turbine capacity (kW)
• Electronics: Power supply ratings, device consumption
