Watt (W)
The watt is the International System of Units (SI) unit of power, named after James Watt, the Scottish inventor. One watt is defined as one joule of work done or energy transferred per second. It is represented by the symbol “W.”
Watts are commonly used to measure the power of electrical devices, such as light bulbs, appliances, and electronic devices. For example, a 60-watt light bulb consumes 60 joules of electrical energy per second, producing light and heat.
Horsepower (hp)
Horsepower is a unit of power that is commonly used to measure the power output of engines, particularly in the context of automobiles and other machinery. The concept of horsepower was originally developed by James Watt to compare the power output of steam engines to the work done by draft horses. There are two common units for horsepower:
How to convert watts to horsepower
For converting watts to horsepower (imperial), divide the number of watts by 745.7:
P(hp) = P(W) / 745.699872
For Example – Convert 250 watts to horsepower
Ans. P(hp) = 250W / 745.699872 = 0.3352 hp

FAQs on Watts to horsepower conversion
What is 1 hp equal to in watts?
1 horsepower (hp) is approximately equal to 745.7 watts (W).
Is 1 hp equal to 1000 watts?
No, 1 horsepower is not equal to 1000 watts. It is approximately equal to 745.7 watts.
क्या 1 hp 1000 वाट के बराबर होता है?
नहीं, 1 हॉर्सपावर 1000 वाट के बराबर नहीं होता है। यह लगभग 745.7 वाट के बराबर होता है।
How many HP is 1000w?
1000 watts (W) is approximately equal to 1.34 horsepower (hp) or 1.36 metric horsepower (PS).
What is 1 hp equal to?
kg Watt is not a standard unit of measurement. It seems to be a combination of kilograms (kg) and watts (W). The two units measure different quantities (mass and power) and cannot be directly converted.
How many volts in 1 kW?
Volts (V) and kilowatts (kW) measure different quantities - voltage and power, respectively. The relationship between them depends on the current flowing through a circuit. In a direct current (DC) circuit, for example, 1 kW of power would be equal to 1000 volts (V) if the current is 1 ampere (A). However, in an alternating current (AC) circuit, the relationship between volts, amps, and kilowatts is more complex and depends on the specific electrical load.
Is 1 hp equal to 1 kW?
No, 1 horsepower is not equal to 1 kilowatt (kW). 1 horsepower is approximately equal to 0.746 kilowatts.
What is 1 kW equal to?
1 kilowatt (kW) is equal to 1000 watts (W). It is a unit of power commonly used for electrical appliances and devices.
