Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 5.1 amps equals 1224 watts. One horse power is 746 watts.
You don't. The units measure different things.
it cant someone in marketing is lying Regarding any electrical equipment, especially motors, 746 watts or volt-amps is 1 horsepower. If your table saw is rated 4 horsepower, that would be 2984 volt-amps and at 110 volts that calculates to 27 amps. The above answer is correct. At 110 volts you cannot run a 4 horsepower motor on a 15 amp circuit. <<>> The above theoretical answer is correct however you should allow extra for efficiency less than 100% and a power factor less than 1, so the current requirement should be increased by 25% to 34 amps. <<>>The rule of thumb for motors at 240 v is 7 amps per HP, which would be 28 amps for 4 HP, but because the voltage is less the current must be more, 28x240/110 which is 61 amps.
FLA is the nameplate amperage rating of the motor when it is running at its designed horsepower and on the motors designed voltage. 746 watts = 1 HP. The FLA of a 1 HP motor at 240 volts would be W = amps x volts, Amps = Watts/Voltage. 746/240 = 3.1 amps full load. Overload the motor and the amps go higher, motor running at no load amps are lower than FLA
Full load amps is the amperage at which the motor was designed to work at to achieve its rated horsepower. Service factor amps is the amount of a periodic overload at which a motor can operate without overload or damage. Continuous operation within the service factor amps will shorten the insulation and motor bearing life of the motor as the motor will be operating at a higher temperature than it was designed to.
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 9.2 amps equals 2208 watts. One horse power is 746 watts.
You are thinking watts to horsepower, not amps to horsepower. Please restate the question.
You don't. The units measure different things.
How to convert horsepower to amps? You'd have to make an assumption about volts. If it's running at 220 volts, that would make it 34 Amps. There are 746 watts in a horsepower and Amps = Watts/Volts.

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

You need to know the voltage as well before the conversion can be made.
The relationship between horsepower (HP) and amps depends on several factors, including the voltage of the electrical system and the efficiency of the device or motor being measured. The relationship can be calculated using the formula: Power (in horsepower) = Voltage (in volts) xCurrent (in amps)/746 Where: Power is measured in horsepower (HP) Voltage is measured in volts (V) Current is measured in amperes (amps) The number 746 is a conversion factor used to convert watts (W) to horsepower (HP). So, if you know the voltage and current of an electrical device, you can use this formula to calculate the power in horsepower. Conversely, if you know the power in horsepower and the voltage, you can rearrange the formula to solve for the current in amps. It's important to note that this formula assumes a certain level of efficiency and power factor for the device being measured. In real-world applications, the actual relationship between horsepower and amps may vary based on factors such as motor efficiency, power factor, and other electrical characteristics.
That will depend on the voltage together with the amperage. Multiply voltage times amperage to get the watts. There are about 746 watts to one horsepower. A 220 volt circuit at 17.60 amps would be about 5.2 horsepower.
