Horsepower to Watt Calculator

What Is Horsepower and Watts

Horsepower (hp) is a unit of power that measures the rate of energy usage over time. It is commonly used to describe the power output of engines and motors.One imperial or mechanical horsepower is equal to 745.7 watts (W), while one metric horsepower is approximately 735.5 watts (W).

A watt (W) is a standard unit of power in the International System of Units (SI). It measures the rate of energy transfer and is defined as one joule per second.Understanding the relationship between horsepower and watts is essential for converting power measurements in various applications.

How to Convert Horsepower to Watts

Imperial/Mechanical Horsepower to Watts

One imperial or mechanical horsepower can be converted to watts as follows:

1 hp(I) = 745.7 W

The conversion formula is:

P(W) = 745.7 × P(hp)

Electrical Horsepower to Watts

One electrical horsepower can be converted to watts as follows:

1 hp(E) = 746 W

The conversion formula is:

P(W) = 746 × P(hp)

Metric Horsepower to Watts

One metric horsepower can be converted to watts as follows:

1 hp(M) = 735.5 W

The conversion formula is:

P(W) = 735.5 × P(hp)
