Conversion Formula
The formula to convert kilowatts to horsepower is: horsepower = kilowatts × 1.34102. This works because 1 kilowatt equals exactly 1.34102 horsepower, based on the international standards. For example, converting 2.2 kW: 2.2 × 1.34102 = 2.950244 horsepower, which is approximately 2.95 hp.
Conversion Example
- Convert 5 kW to horsepower:
- Step 1: Write the formula: hp = 5 × 1.34102
- Step 2: Multiply: 5 × 1.34102 = 6.7051
- Step 3: Result: 6.7051 horsepower
- Convert 10 kW to horsepower:
- Step 1: Use hp = 10 × 1.34102
- Step 2: Multiply: 10 × 1.34102 = 13.4102
- Step 3: Result: 13.4102 horsepower
- Convert 1.5 kW to horsepower:
- Step 1: Apply hp = 1.5 × 1.34102
- Step 2: Multiply: 1.5 × 1.34102 = 2.01153
- Step 3: Result: 2.01153 horsepower

Conversion Definitions
kw, or kilowatt, is a measure of power equal to 1,000 watts, used to quantify electrical power or the rate of energy transfer. It is commonly used for engines, motors, and electrical systems to indicate how much energy is produced or consumed per unit time.
Horsepower is a unit of power originally developed to compare the power of engines to horses, equal to approximately 745.7 watts, used mainly in automotive and mechanical contexts to express the power output of engines or motors.
Conversion FAQs
How accurate is the conversion from 2.2 kw to horsepower?
The conversion is precise because it relies on a fixed factor of 1.34102, ensuring that 2.2 kW equals exactly 2.950244 horsepower. Small variations may occur due to rounding but are negligible for most practical uses.
Can I use this conversion for both electrical and mechanical power?
Yes, because the conversion factor applies universally for power measurements, whether it’s electrical power in kilowatts or mechanical power in horsepower, assuming the power source is consistent and efficient.
Why do some sources use different conversion factors?
Different standards or contexts might lead to slight variations in the factor, but the generally accepted value is 1.34102. Some older or region-specific sources might use rounded or approximate values, causing minor discrepancies.
Is horsepower still used in modern power measurements?
While the watt-based system is more universal, horsepower remains popular especially in automotive, manufacturing, and certain engineering fields, providing a familiar way to compare engine and motor capabilities.
