Conversion Relationships

Basic Relationships(Based on Watts)

1 Kilowatt (kW) = 1,000 Watt (W)
1 Mégawatt (MW) = 1,000,000 Watt (W)
1 Gigawatt (GW) = 1,000,000,000 Watt (W)
1 Milliwatt (mW) = 0.001 Watt (W)
1 Cheval-vapeur (hp) ≈ 745.699872 Watt (W)
1 Cheval-vapeur métrique (PS) ≈ 735.49875 Watt (W)
1 British Thermal Unit/Heure (BTU/h) ≈ 0.293071 Watt (W)
1 Kilogramme-force mètre/Seconde ≈ 9.80665 Watt (W)
1 Kilocalorie/Heure ≈ 1.163 Watt (W)
1 Foot-pound force/Seconde ≈ 1.35582 Watt (W)

Common Conversions

1 Cheval-vapeur (hp) ≈ 0.7457 Kilowatt (kW)
1 Kilowatt (kW) ≈ 1.341 Cheval-vapeur (hp)
1 Cheval-vapeur métrique (PS) ≈ 0.73550 Kilowatt (kW)
1 Kilowatt (kW) ≈ 1.36 Cheval-vapeur métrique (PS)
1 Air Conditioner Horsepower ≈ 735 Watt ≈ 1 Cheval-vapeur métrique
3412 BTU/h ≈ 1 Kilowatt (kW)

Horsepower Type Description

Mechanical Horsepower (hp):Imperial Units,1 hp = 550 ft·lbf/s
Cheval-vapeur métrique (PS):German Standard,1 PS = 75 kgf·m/s
Electrical Horsepower:1 Electrical Horsepower = 746 W(Exact Value)
Chinese Air Conditioner"Cheval-vapeur":1Cheval-vapeur ≈ 735W ≈ 1 PS

Power Definition

Power (P) = Energy (E) / Time (t)
1 Watt = 1 Joule/Seconde (1 W = 1 J/s)
Electric Power:P = Voltage × Current (P = U × I)
Mechanical Power:P = Force × Speed (P = F × v)

À propos des unités de puissance:

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。

Cheval-vapeur (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"Cheval-vapeur"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。
