Depends upon the voltage. At 110 volts, 800 watts = 7.27 amps. At 115 volts, 800 watts = 6.96 amps. At 120 volts, 800 watts = 6.67 amps. At 220 volts, 800 watts = 3.64 amps. Just divide the wattage by the voltage to determine the amperage. (You can also divide the wattage by the amperage to determine the voltage!)
Power is simply a rate -the rate of transfer of energy. The watt is simply the SI unit of power, whereas the horsepower is an Imperial unit of power. In other words, watts and horsepower both measure the same thing, and can be used interchangeably. If you wish, you could measure the power of an electric heater in horsepower, for example. A horsepower is equivalent to 746 watts. In most countries outside the United States, the horsepower is considered obsolete and, for this reason, the output of motors (including automobile engines) are measured in watts (or kilowatts), not horsepower.
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
Divide by 745.7 the formula is watts over Current times volts so if you want to know how many amps you are using you would divide the volts into the watts that will give you the current(amps) needed to drive this device by the same token you can use the formula to find the volts by dividing the current into the watts. if two elements are known you can determine the unknown factor. if you know the amperes and the voltage you just multiply volts time amperes and you find the watts . confusing isn't it ? example 110 volts X 10 Ampere's 1,100 watts . so you would have about almost a horse and a half motor or device .
LRA is not any known unit of measure. You can convert horsepower to BTU per hour, calories per second, ergs per second, watts, Kilowatts, MW, GW, etc.
You are trying to compare apples and donuts. 179cc is a size of engine that would have a fairly wide range of horsepowers. Horsepower is a power rating.
To convert watts to horsepower, you can use the conversion factor where 1 horsepower is approximately equal to 745.7 watts. To convert 2250 watts to horsepower, divide 2250 by 745.7. Doing this calculation gives you about 3.02 horsepower. Thus, 2250 watts is approximately 3.02 hp.
1 hp = 745.699872 watts
Watts x 0.001341 = hp
To convert horsepower to watts, multiply the horsepower value by 745.7. This conversion factor is based on the definition of one horsepower being equivalent to 745.7 watts. For example, if you have 100 horsepower, the conversion to watts would be 100 hp * 745.7 = 74570 watts.
To convert Watts (W) to a horsepower rating (HP) simply multiply the Watts by 0.00134 W x 0.00134 = HP
A total of 1200 watts is equal to 1200/746 = 1.6 horsepower.
One HP equals 746 watts. So 4 HP = 2984 watts.
1 HP = 750 watts / 5250 divided by 750 = 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.

1 horsepower = 746 watts, 1 watt = 1 volt x 1 amp => 20 Horsepower = 14,920 watts => 14,920 watts / 220 volts = 67.82 amps
