What unit is approximately 745 watts?

Power may be measured in a unit called the horsepower. One horsepower is the amount of work a horse can do in 1 minute, which equals 745 watts of power.

Why did Watts invented horsepower?

James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented. Watt measured the capability of a big horse to pull a load and found it could pull a weight of 150-pounds while walking at 2.5 miles per hour.

What is the origin of horsepower?

The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery.

What does 1hp equal to?

746 watts
The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.

How many watts does it take to create one horsepower?

One electric horsepower is equal to exactly 746 watts.

How was horsepower determined?

Calculating the Power of a Single Horse Each horse pushed with a force that Watt estimated at 180 pounds. From this, Watt calculated that one horsepower was equivalent to one horse doing 33,000 foot-pounds of work in one minute. That amount of work equals one horsepower.

Although Watt invented and improved a number of industrial technologies, he is best remembered for his improvements to the steam engine. Watt’s steam engine design incorporated two of his own inventions: the separate condenser (1765) and the parallel motion (1784).

How many watts is 746 hp?

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

How many watts in 1 horsepower?

Horsepower (hp) is the name of several units of measurement of power, the rate at which work is done. This tool converts horsepower to watts (hp to w) and vice versa. 1 horsepower ≈ 745.7 watts. The user must fill one of the two fields and the conversion will become automatically.

How do you convert hp to W in Watts?

1 hp(E) = 746 W. So the power conversion of horsepower to watts is given by: P (W) = 746 ⋅ P (hp) Example. Convert 10 hp to watts: P (W) = 746 ⋅ 10hp = 7460 W . Metric horsepower to watts. One metric horsepower is equal to 735.49875 watts: 1 hp(M) = 735.49875 W.

What is the P(W) of 1 hp?

One mechanic or hydraulic horsepower is equal to 745.699872 watts: 1 hp(I) = 745.699872 W. So the power conversion of horsepower to watts is given by: P (W) = 745.699872 ⋅ P (hp)
