Horsepower Type Description

Mechanical Horsepower (hp)：Imperial Units，1 hp = 550 ft·lbf/s

Metric Horsepower (PS)：German Standard，1 PS = 75 kgf·m/s

Electrical Horsepower：1 Electrical Horsepower = 746 W（Exact Value）

Chinese Air Conditioner"Horsepower"：1Horsepower ≈ 735W ≈ 1 PS

Power Definition

Power (P) = Energy (E) / Time (t)

1 Watt = 1 Joule/Second (1 W = 1 J/s)

Electric Power：P = Voltage × Current (P = U × I)

Mechanical Power：P = Force × Speed (P = F × v)

About Power Units:

Watt (W)：Basic Unit of Power in the International System of Units，1Watt Equals Per Second1Joule Energy Conversion Rate。By Scottish inventor James·Named after Watt。

Horsepower (hp)：Traditional Power Unit，Originally Used to Compare the Work Capacity of Steam Engines and Horses。Mechanical Horsepower（Imperial）Approximately Equals745.7Watt，Metric Horsepower Approximately Equals735.5Watt。Common Unit for Car Engine Power。

Kilowatt (kW)：Common Practical Unit，1Kilowatt=1000Watt。Household Appliance Power、Electric Motor Power is Usually Measured in Kilowatts。Electricity Billing Unit"Kilowatt-hour"(kWh)Is Power×Energy Unit of Time。

Air Conditioner Horsepower：Used in China's Air Conditioning Industry"Horsepower"As a Unit of Cooling Capacity，1Equivalent to735Watt（Approximate Actual2500Watt Cooling Capacity）。1Electric Power of One Horsepower Air Conditioner Approximately735W，1.5Horsepower Approximately1100W，2Horsepower Approximately1470W。

Application Scenarios：This Tool is Suitable for Electrical Engineering、Mechanical Engineering、Car Parameter Comparison、Home Appliance Selection、Scenarios like Power Generation Calculation。Distinguish from Power（Watt）And Energy（Watt-hour）Concept of。
