To convert horsepower (hp) to watts, you can use the conversion factor where 1 hp is approximately equal to 746 watts. Therefore, a 7.0 hp lawnmower would be around 5,222 watts (7.0 hp x 746 watts/hp).
One hp is 735.5 watts.
according to google calculator "1 hp in watts": 1 hp = 745.699872 watts
2.0 horsepower = 1 491.39974 watts
A 4 horsepower (hp) lawnmower is approximately equivalent to 2,983 watts. This conversion is based on the standard that 1 hp is equal to about 745.7 watts. Therefore, to convert 4 hp to watts, you multiply 4 by 745.7.
To convert watts to horsepower, you can divide the number of watts by 746 (since 1 horsepower is equal to 746 watts). For example, if you have 1000 watts, the conversion would be 1000 watts / 746 = approximately 1.34 horsepower.
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
To convert Watts (W) to a horsepower rating (HP) simply multiply the Watts by 0.00134 W x 0.00134 = HP
To convert watts to horsepower, you can use the conversion factor where 1 horsepower (hp) is equal to approximately 746 watts. To determine the minimum hp needed to drive the generator delivering 180 watts, you divide 180 watts by 746 watts/hp. This calculation yields about 0.241 hp. Therefore, at least 0.241 hp is required to drive the generator.
746 watts = 1 HP
1 horsepower is = 746 watts 746 x .75 = 559.5 watts
1hp = 746 watts, so 2hp would be 1492 watts, or almost 1.5 kw kWh does not convert to hp, as kWh has a time component.
