Common Values Table
Quick reference chart for frequently used power values (0.5 to 1000 kW) converted to mechanical HP, metric PS, and electric HP.
A kilowatt (kW) is a unit of power equal to 1,000 watts. It is a standard SI-derived unit used to measure the rate of energy transfer or conversion. Named after the Scottish engineer James Watt, the kilowatt is commonly used to express the output power of engines, electric motors, generators, and the power consumption of electrical devices.
In everyday life, kilowatts are used to measure electricity consumption (kilowatt-hours on your utility bill), the power output of household appliances (a microwave might use 1-2 kW), and industrial machinery. The kilowatt is the preferred metric unit for power, while horsepower remains widely used in automotive and certain engineering contexts, especially in countries that use imperial measurements.
What Is Horsepower?
Horsepower (HP) is a unit of power that was originally defined by James Watt in the late 18th century to compare the power output of steam engines to the work done by draft horses. Today, there are several different definitions of horsepower used in various applications:
Mechanical Horsepower (HP) — The imperial horsepower, equal to 745.7 watts. Used primarily in the United States and the United Kingdom for automotive and mechanical applications. 1 kW = 1.34102 mechanical HP.
Metric Horsepower (PS) — Also called Pferdestärke (PS) in German, equal to 735.5 watts. Used in Europe and many other parts of the world. 1 kW = 1.35962 PS.
Electric Horsepower — A slightly different unit equal to 746 watts, used specifically for electric motors. 1 kW = 1.34048 electric HP.
Our converter handles all three types, giving you complete flexibility regardless of which horsepower standard you need.
Why Convert Between Kilowatts and Horsepower?
Converting between kilowatts and horsepower is essential for a wide range of practical applications:
Automotive Specifications: European cars typically list engine power in kilowatts (kW) or metric horsepower (PS), while American and British vehicles use mechanical horsepower (HP). A car with 150 kW produces approximately 201 HP.
Electric Motors: Electric motors are often rated in kilowatts, while the equipment they power may specify requirements in horsepower. Understanding both units is essential for proper motor selection.
Industrial Equipment: Pumps, compressors, generators, and other industrial machinery may be rated in either kW or HP depending on the manufacturer and target market.
International Standards: Engineers working on global projects must frequently convert between kW and HP to meet different regional standards and specifications.
Energy Management: Understanding power ratings in both units helps with energy consumption analysis, equipment sizing, and efficiency comparisons.
Understanding Power Scales
Here's a quick comparison to help you visualize power values:
1 kW — Approximately 1.34 HP (mechanical). About the power of a small electric heater or a kitchen microwave.
50 kW — About 67 HP. A typical compact car engine output.
75 kW — About 100 HP (mechanical). A small to mid-size family car.
150 kW — About 201 HP. A powerful family sedan or sports car.
300 kW — About 402 HP. A high-performance sports car or small truck.
1,000 kW (1 MW) — About 1,341 HP. Large industrial generators and heavy machinery.
Whether you're comparing car specifications, selecting an electric motor, or working on an engineering project, this converter provides accurate, instant results across all common horsepower types.
Frequently Asked Questions
How many horsepower are in 1 kilowatt?
One kilowatt is equal to 1.34102 mechanical horsepower, 1.35962 metric horsepower (PS), or 1.34048 electric horsepower. The exact conversion depends on which type of horsepower you are using. In automotive contexts, 1 kW is commonly approximated as 1.34 HP for quick calculations. Our converter uses precise factors for maximum accuracy.
How do I convert kilowatts to horsepower manually?
To convert kilowatts to mechanical horsepower, multiply the number of kilowatts by 1.34102. For example: 100 kW × 1.34102 = 134.10 HP. For metric horsepower (PS), multiply by 1.35962 instead (100 kW × 1.35962 = 135.96 PS). To convert horsepower back to kilowatts, divide the HP value by the same factor. For quick mental conversions, you can use the approximation 1 kW ≈ 1.34 HP.
What is the difference between mechanical HP, metric HP, and electric HP?
Mechanical horsepower (HP) is the imperial unit equal to 745.7 watts, used primarily in the US and UK for automotive and mechanical applications. Metric horsepower (PS) is equal to 735.5 watts and is used in Europe and many other parts of the world. Electric horsepower is defined as exactly 746 watts and is used for electric motors. The difference between them is small but matters for precise engineering work. 1 kW = 1.34102 mechanical HP = 1.35962 metric HP = 1.34048 electric HP.
Why do cars in Europe use kW and PS instead of HP?
European countries primarily use the metric system, so they measure engine power in kilowatts (kW) or metric horsepower (PS). The term "PS" comes from the German "Pferdestärke," which means "horse strength." While PS is the traditional unit used by European automotive manufacturers, modern European vehicle specifications increasingly list power in kilowatts to align with international SI standards. For example, a Volkswagen Golf GTI typically produces about 180 kW (245 PS or 241 mechanical HP).
What is the difference between a kilowatt and a kilowatt-hour?
A kilowatt (kW) is a unit of power — the rate at which energy is generated or consumed. A kilowatt-hour (kWh) is a unit of energy — the amount of energy consumed over time. Think of it like speed versus distance: kilowatts are like speed (how fast energy is used), while kilowatt-hours are like distance (how much energy has been used). A 1 kW device running for 1 hour consumes 1 kWh of energy. Our converter focuses on power (kW to HP), while energy conversions require a different calculation.
