About Kilowatts (kW) to Horsepower (hp) Conversion

What are Kilowatts and Horsepower?

Kilowatts (kW) and horsepower (hp) are both units used to measure power, but they originate from different systems:

• Kilowatt (kW): A unit of power in the International System of Units (SI). It's widely used to measure electrical power and the power output of engines in many parts of the world.
• Horsepower (hp): A unit of power introduced by James Watt in the late 18th century. It's commonly used in the automotive industry, especially in the United States, to describe the power output of engines.

Formula for Kilowatts to Horsepower Conversion

The formula to convert kilowatts to horsepower is:

\[hp = kW \times 1.34102\]

Where:

• \(hp\) is the power in horsepower
• \(kW\) is the power in kilowatts
• \(1.34102\) is the conversion factor

Calculation Steps

1. Identify the power in kilowatts.
2. Multiply the kilowatt value by 1.34102.
3. The result is the equivalent power in horsepower.

Example

Let's convert 75 kilowatts to horsepower:

1. Given: \(kW = 75\)
2. Apply the formula: \(hp = 75 \times 1.34102\)
3. Calculate: \(hp = 100.5765\)
4. Rounding to 2 decimal places: \(hp \approx 100.58\)

Visual representation:

Therefore, 75 kilowatts is equivalent to approximately 100.58 horsepower.
