# Watt to Hp Watt and horsepower both are the units of power. Power in horsepower is equal to 1340 times of power in watts divided by 1000. For converting Power P(W) in watts to power P(HP) in horsepower use the formula.

Horsepower is calculated from the watts as a SI unit for measuring power is calculated. Learn to calculate Watt to hp.

## Meaning of Watt:

The Watt equals one joule per second. For example, if a 60W lamp remains on for one hour, the power consumed is 60 watts-hour. The name of this power unit is a tribute to the British engineer James Watt, for the recognition of the many researches that he made, to better understand the energy, as well as, the way in which he created machines that obtained a better use of it.

## Meaning of Horsepower:

The Horsepower came about when, for the first time in history, people had something like power to use other than animal traction. Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.

To be more precise in assessing this unit of measure, James Watt has carried out various experiments in order to measure the work performed by a horse for a certain period of time. From there he just needed to see how long it took his steam engine to do the same job.

## What is the international acronym for each of these two power units?

### Prefix or symbol for horsepower is: hp

Technical units conversion tool for power measures. Exchange reading in watts unit W into horsepower unit hp as in an equivalent measurement result (two different units but the same identical physical total value, which is also equal to their proportional parts when divided or multiplied).

One watt converted into horsepower equals = 0.0013 hp
1 Watt = 0.0013 hp

## How to convert Watts to Horsepower?

Watts to mechanic / hydraulic horsepower
One mechanic or hydraulic horsepower is equal to 745.699872 watts:

1 hp(I) = 745.699872 W
So the power conversion of watts to horsepower is given by:
P(hp) = P(W) / 745.699872

Example
Convert 10Watt to mechanic horsepower:
P(hp) = 10W / 745.699872 = 0.01341 hp

Watts to electrical horsepower
One electrical horsepower is equal to 746 watts:
1 hp(E) = 746 W
So the power conversion of watts to horsepower is given by:
P(hp) = P(W) / 746

Example
Convert 10W to electrical horsepower:
P(hp) = 10W / 746 = 0.013405 hp

Watts to metric horsepower
One metric horsepower is equal to 735.49875 watts:
1 hp(M) = 735.49875 W
So the power conversion of watts to horsepower is given by:
P(hp) = P(W) / 735.49875

Example
Convert 10W to metric horsepower:
P(hp) = 10W / 735.49875 = 0.013596 hp

## What is the power of 1hp?

746 watts
A power level of 1 hp is approximately equivalent to 746 watts (W) or 0.746 kilowatts (kW). To convert from horsepower to watts, multiply by 746. To convert from watt to hp, multiply by 0.00134.
