About Horsepower to Kilowatts Conversion

What is Horsepower and Kilowatts?

Horsepower (hp) and kilowatts (kW) are both units used to measure power, particularly in the context of engines and motors.

• Horsepower (hp): A unit of power originally created by James Watt to compare the output of steam engines with the power of draft horses. It's still widely used, especially in the automotive industry.
• Kilowatt (kW): The standard unit of power in the International System of Units (SI). It represents 1,000 watts and is commonly used in electrical and mechanical applications.

Formula for Horsepower to Kilowatts Conversion

The formula to convert horsepower to kilowatts is:

\[kW = hp \times 0.7457\]

Where:

• \(kW\) is the power in kilowatts
• \(hp\) is the power in horsepower
• \(0.7457\) is the conversion factor

Calculation Steps

1. Identify the power in horsepower.
2. Multiply the horsepower value by 0.7457.
3. The result is the equivalent power in kilowatts.

Example

Let's convert 100 horsepower to kilowatts:

1. Given: \(hp = 100\)
2. Apply the formula: \(kW = 100 \times 0.7457\)
3. Calculate: \(kW = 74.57\)

Visual representation:

Therefore, 100 horsepower is equivalent to 74.57 kilowatts.
