Horsepower to Watt Conversion:

Watt to Horsepower Conversion:

One horsepower is equal to 745.7 watts. So, to convert a horsepower to watts, we multiply the horsepower value by 745.7. To convert watts to horsepower, we divide watts by 745.7. With these formulas, you can easily convert horsepower to watts.

What is Horsepower?

Horsepower is a unit used to measure the performance of a machine or engine. The term is referred to by the name “horsepower” because it was first developed in the 18th century by the English inventor James Watt to express the power of steam engines. One horsepower is equivalent to a force equal to a weight dragged one foot for one minute with a force of 550 pounds. In modern usage, a horsepower is used to refer to how much power an engine or machine can produce. Horsepower is usually measured in units of horsepower (hp).

What is a Watt?

A watt is a unit of measurement of electrical power. It is named after the Scottish engineer James Watt and is the most widely used of the units of power in the metric system. A watt refers to the rate of energy conversion or rate of energy transfer in a system. One watt means that one joule (a unit of energy) is used for one second, or one joule of energy is expended in one second. Watts are used to measure the power of electric motors, light bulbs, electrical appliances and other electrical systems.

Mathematical Relationship Between Horsepower and Watts

The mathematical relationship between horsepower and watts is expressed as follows:

1 horsepower (hp) ≈ 745.7 watts (W)

To put this more clearly, one horsepower is approximately equal to 745.7 watts. So when a power value is given in horsepower, we can multiply it by 745.7 to express that value in watts. Similarly, when a power value is given in watts, we can divide by 745.7 to express that value in horsepower. This conversion establishes a mathematical relationship between horsepower and watts and allows us to convert between these two units.

Horsepower to Watt (Hp to W) Conversion Calculation Example

Example:

A vehicle has 150 horsepower. Let’s calculate this value in watts.

Solution:

To convert horsepower to watts, we multiply the horsepower value by 745.7.

Watt = Horsepower × 745.7

Given horsepower value: 150 hp

Watt = 150 × 745.7

Watt = 111855

In this case, 150 horsepower is approximately equal to 111855 watts.

As in this example calculation, we convert horsepower to watts. Conversely, to convert watts to horsepower, we divide by 745.7.
