There is no proof. 1 mechanical horse power is simply defined as 745.7 watts. Period.
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
They have the same physical dimensions but not the same size. 1 horsepower = 746 watts .
1 horsepower is 746 watts. You would need approximately 1340.5 horsepower to produce 1 megawatt of energy. That's a lot of horses!
Power in horsepower (hp) can be calculated using the formula: [ \text{hp} = \frac{\text{Torque (lb-ft)} \times \text{RPM}}{5252} ] This formula relates torque (in pound-feet) and rotational speed (in revolutions per minute, RPM) to derive horsepower. Alternatively, for electrical power, it can be calculated as: [ \text{hp} = \frac{\text{Watts}}{746} ] where Watts is the power in watts.
One horsepower is equivalent to approximately 746 watts in electrical power. This unit of measurement originated in the 18th century to compare the output of steam engines to that of draft horses. In terms of mechanical work, it can also be defined as the ability to perform 550 foot-pounds of work per second.
746 watts equals one horsepower.
2 horsepower is equal to approximately 1492 watts.
1hp equals 746 watts.2.2kw equals 2200 watts divided by 746 equals 2.95 hp
746 watts is equal to 1 horsepower. Horsepower is a unit of power that measures the rate at which work is done, and 1 horsepower is equivalent to 746 watts.
746 watts per horsepower
One HP equals 746 watts. So 4 HP = 2984 watts.
A horsepower is equal to 746 watts, so 10 x 746 = 7,460 watts.
746 watts.
A total of 1200 watts is equal to 1200/746 = 1.6 horsepower.
Kilowatts (kW) and horsepower (hp) are both units of power, but they represent power in different systems of measurement. One horsepower is equivalent to about 0.746 kilowatts. Kilowatts are the international standard for power measurement, while horsepower is commonly used in the United States and some other countries.
1 horsepower equates to about 745.7 watts.Horsepower is simply the Imperial unit of measurement of power, whereas the watt is the SI unit for power. So there's nothing stopping you from specifying the power output of an electric heater in horsepower if you want to, or specifying the output power of a car engine in watts (as they do outside the United States). But, to answer your question, there are 746 W to one horsepower.
The number to use for calculation purposes is 746 watts equals one horsepower.
