The conversion of 5.5 kilowatts (kW) equals approximately 7.38 horsepower. This means that a device or engine rated at 5.5 kW produces about 7.38 horsepower of power output.
To convert kilowatts to horsepower, the standard formula multiplies the power in kilowatts by 1.34102. This conversion factor originates from the relationship between the metric power unit (kilowatt) and the imperial unit (horsepower). For example, 5.5 kW multiplied by 1.34102 equals roughly 7.38 horsepower, providing a straightforward way to understand power measurements across different systems.

Conversion Formula
The formula used to convert kilowatts to horsepower is: HP = kW × 1.34102. This works because 1 kilowatt equals approximately 1.34102 horsepower. The number 1.34102 is derived from the relationship between the metric power unit and the imperial horsepower. For example, converting 5.5 kW:
- Multiply 5.5 by 1.34102
- 5.5 × 1.34102 = 7.37561
- Rounded to four decimal places, it becomes 7.3756 horsepower
Conversion Example
- Convert 10 kW to horsepower:
- Step 1: Write down the formula: HP = kW × 1.34102
- Step 2: Multiply 10 by 1.34102
- 10 × 1.34102 = 13.4102
- Result: 10 kW equals 13.4102 horsepower
- Convert 2.2 kW to horsepower:
- Step 1: Use the formula: HP = kW × 1.34102
- Step 2: Multiply 2.2 by 1.34102
- 2.2 × 1.34102 = 2.95024
- Result: 2.2 kW is approximately 2.9502 horsepower
- Convert 0.75 kW to horsepower:
- Step 1: Apply the formula: HP = kW × 1.34102
- Step 2: Multiply 0.75 by 1.34102
- 0.75 × 1.34102 = 1.00577
- Result: 0.75 kW equals about 1.0058 horsepower

Conversion Definitions
kw
KW, or kilowatt, is a metric unit of power equal to 1,000 watts. It measures the rate at which energy is produced or consumed in electrical devices or engines, providing a standard for assessing power output across various systems and applications.
horsepower
Horsepower is an imperial unit of power that quantifies the rate of work done, roughly equivalent to 745.7 watts. It is used to rate engines, motors, and other machinery, helping compare the power of different devices regardless of their size or type.
Conversion FAQs
Why is 1 kW equal to 1.34102 horsepower?
This conversion factor comes from the relationship between the metric watt and the imperial horsepower. Since 1 horsepower equals approximately 745.7 watts, dividing 745.7 by 1,000 gives about 0.7457. Then, 1 divided by 0.7457 results in roughly 1.34102, establishing the conversion rate.
Can I convert kilowatts to horsepower manually without a calculator?
Yes, but it requires multiplying the number of kilowatts by 1.34102. For example, if you have 5.5 kW, multiply 5.5 by 1.34102 to get the horsepower. Using a calculator speeds up the process and reduces errors, especially with larger numbers.
Is horsepower used only in the United States?
Horsepower is primarily used in the United States and some other countries for measuring engine power, especially in automobiles and machinery. In many countries, metric units like kilowatts are preferred, but horsepower remains a common standard in specific industries.
