Supported Power Units

• Watts (W): The SI unit of power, equivalent to one joule per second
• Kilowatts (kW): 1,000 watts, commonly used for larger power ratings
• Horsepower (hp): Mechanical horsepower, approximately 745.7 watts

Conversion Factors

• 1 Watt (W) = Base unit
• 1 Kilowatt (kW) = 1,000 W
• 1 Horsepower (hp) = 745.7 W (mechanical horsepower)
• 1 kW ≈ 1.341 hp
• 1 hp ≈ 0.7457 kW

Types of Horsepower

This converter uses mechanical horsepower (745.7 W), which is the most common standard. Other types include:

• Metric horsepower (PS): 735.5 W (used in Europe)
• Electrical horsepower: 746 W
• Boiler horsepower: 9,809.5 W

For most automotive and mechanical applications, mechanical horsepower is the standard.

Common Use Cases

Tips for Accurate Conversions

1. Horsepower Type: Verify whether specifications use mechanical, metric, or electrical horsepower
2. Regional Differences: European cars often use kW, American cars use hp
3. Precision: Results display up to 4 decimal places for accuracy
4. Peak vs Continuous: Some ratings show peak power, others show continuous power
5. Efficiency: Actual output power may be less than rated power due to efficiency losses
