Horsepower to Watts Conversion
To convert horsepower to watts, we can use the formula:
1 horsepower = 746 watts
Therefore, the correct option is A, which is 746 watts.
Explanation:
- Horsepower (hp) is a unit of power, which is defined as the power required to lift 550 pounds of weight at a rate of one foot per second.
- Watt (W) is also a unit of power, which is defined as the rate of energy transfer or the rate at which work is done.
- The conversion factor between horsepower and watts is 746, which means that 1 horsepower is equal to 746 watts.
- This conversion factor is based on the definition of horsepower and the definition of watt, which are both derived from the fundamental units of mass, length, and time in the International System of Units (SI).
- Therefore, to convert horsepower to watts, we simply need to multiply the horsepower value by 746.
Conclusion:
In conclusion, 1 horsepower is equal to 746 watts. This conversion factor is important in many applications, especially in the automotive and engineering industries, where horsepower is commonly used to measure the power output of engines and motors.
