Definition of KW and HP

Explanation Section
    A kilowatt (kW) is a SI unit of power and is used to measure the rate of doing work.
  • The word "kilowatt" is derived from "kilo," which means one thousand, and the word "watt," is named after James Watt. A kilowatt is a Kilojoule/second.
  • The watt is defined as the power required to operate a light bulb that consumes one joule of energy per second. The kilowatt is equal to one thousand watts.
  • The kilowatt is used to measure the power output of electrical appliances and devices, as well as the power output of power plants.
  • Here are some examples of how kilowatts are used:
    • A household refrigerator uses about 1 kW of power.
    • A washing machine uses about 2 kW of power.
    • A air conditioner uses about 3 kW of power.
    • A car engine uses about 100 kW of power.
    • A industrial motor uses about 1,000 kW of power.
    • A nuclear power plant can generate over 1,000,000 kW of power.
  • A Horsepower (HP) is also a unit of power equal to 746 watts. It is an imperial unit and is commonly used to measure the power of mechanical devices, such as car engines and industrial motors.
  • One horsepower is defined as the power required to lift 550 pounds one foot in one second. It was coined by James Watt to compare the output of his steam engines to the power of horses.
  • Horsepower is typically used to compare engine performance. In general, engines with more horsepower are more powerful and can accelerate faster but may consume more fuel.
  • Here are some examples of how horsepower is used:
    • A car engine has between 100 and 300 horsepower.
    • A truck engine has between 200 and 500 horsepower.
    • A motorcycle engine has between 50 and 150 horsepower.
    • A industrial motor has between 1 and 1000 horsepower.
  • Horsepower is also used to measure the power output of aircraft engines and boat engines.

Use of KW To HP Converter Tools

Explanation Section
  • Kilowatts (kW) and horsepower (HP) are both units of power.

  • Kilowatt is the SI unit of power, while horsepower is an imperial unit. The SI unit system is the international standard system of units, and is used in most countries around the world. However, horsepower is still commonly used in some countries, especially the United States.
  • Kilowatt is typically used to measure the power of electrical appliances and devices, while horsepower is typically used to measure the power of mechanical devices such as motors, compressors
  • Many older devices and machines are rated in horsepower, while many newer devices and machines are rated in kilowatt.
  • In order to compare the power of these devices and machines which use different specifications, we need to be able to convert between horsepower and kilowatt.
  • Buying a New Vehicle: Bike, Car or Truck engines are typically rated in horsepower or brake horse power. However, fuel efficiency is typically measured in liters per 100 kilometers. In order to compare the fuel efficiency of different cars, we need to be able to convert horsepower to kilowatt.
  • Home Appliances - Motors/Geysers/Generators: Generators are typically rated in kilowatt. Motors, Compressors may be in horsepower. In order to choose the right generator or motor to withstand the load, we need to convert between hp and kW
  • Electricity/Power Bill: Power bills typically show the amount of energy consumed in kilowatt-hours. However, some appliances and devices are rated in horsepower. For calculations and for purpose of comparison and understand energy consumption, we use the converter to convert from kilowatt to horsepower and horsepower to kilowatt hour.

Frequently Asked Questions on hp to kw and kw to hp conversion

FAQ icon

  • Horsepower is a unit of power used for measuring how powerful an engine is 1 horsepower is equivalent to 746 watts. So if you took a 1-horsepower horse and put it on a treadmill, it could operate a generator producing a continuous 746 watts.

  • "Brake horse power is the actual horse power that the vehicle is performing at It is denoted as BHP. It takes into account power/friction losses. Horsepower is the amount of horse power that it is designed for and does not take into account power / friction losses

  • hp is always greater than bhp. bhp is approximately 0.99 x hp (assuming some losses due to friction)

  • 1 horsepower is equal to 745.7 watts
