How many HP is 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.
What is the relation between 1 horsepower and Watt?
746 watt s
A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW). To convert from horsepower to watts, multiply by 746.
Why did James Watt call it 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.
How much horsepower does a horse have?
Power of a horse In fact, the maximum output of a horse can be up to 15 horsepower, and the maximum output of a human is a bit more than a single horsepower.
How much power in watts is equal to 2 horsepower?
Watts to horsepower conversion table
| Watts (W) | Mechanic horsepower (hp(I)) | Metric horsepower (hp(M)) |
|---|---|---|
| 1 W | 0.001341 hp | 0.001360 hp |
| 2 W | 0.002682 hp | 0.002719 hp |
| 3 W | 0.004023 hp | 0.004079 hp |
| 4 W | 0.005364 hp | 0.005438 hp |
Is horsepower the same as Watts?
One electric horsepower is equal to exactly 746 watts. The electric horsepower is a US customary and imperial unit of power. Electric horsepower can be abbreviated as hp(E); for example, 1 electric horsepower can be written as 1 hp(E).
How many horsepower is a human?
1.2 hp
When considering human-powered equipment, a healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude) and sustain about 0.1 hp (0.075 kW) indefinitely; trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours.
Can a human generate one horsepower?
When considering human-powered equipment, a healthy human can produce about 1.2 hp (0.89 kW) briefly (see orders of magnitude) and sustain about 0.1 hp (0.075 kW) indefinitely; trained athletes can manage up to about 2.5 hp (1.9 kW) briefly and 0.35 hp (0.26 kW) for a period of several hours.
How do you convert horsepower to Watts?
A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW). To convert from horsepower to watts, multiply by 746. To convert from watts to horsepower, multiply by 0.00134.
How do you calculate horsepower?
To calculate the horsepower of a car, start by finding the engine’s torque value and engine speed in the owner’s manual. Multiply the torque by the engine speed, and then divide that number by 5252. The answer is the horsepower for the car’s engine.
How many watts are in a horsepower?
One mechanical horsepower unit is approximately equal to 745.7 watts. One electrical horsepower, used for rating electrical motors, is equal to 746 watts. Horse power was originally defined as the power output of a single common draft animal. One horse could sustain the work of 1 horsepower.
How many watts in a hp?
Metric horsepower to watts. One metric horsepower is equal to 735.49875 watts: 1 hp(M) = 735.49875 W. So the power conversion of horsepower to watts is given by: P(W) = 735.49875 ⋅ P(hp)
