📐 What Is Horsepower?

Horsepower (HP) is a unit of power commonly used to measure the output of engines and motors. It originated during the industrial revolution and was standardized by James Watt to quantify the performance of steam engines. Today, mechanical horsepower (also known as imperial horsepower) is defined as:

1 horsepower = 745.699872 watts
or
1 horsepower = 0.7457 kilowatts

🔌 What Is a Kilowatt?

A kilowatt (kW) is a metric unit of power equal to 1,000 watts. It’s used widely around the world to quantify power, especially in electric appliances, vehicles, and industrial machinery. Converting horsepower to kilowatts is essential when comparing engine output across different measurement systems.

🛠️ How This Converter Works

Our horsepower to kilowatts converter uses the standardized conversion factor:

1 HP = 0.7457 kW
1 kW = 1.341 HP

This means:

To convert from horsepower to kilowatts, multiply by 0.7457
To convert from kilowatts to horsepower, divide by 0.7457

But why do the math manually when this tool does it instantly and error-free?
