Horse power (more correctly brake horse power, usually abbreviated to "bhp") is a measure of how fast energy is being used. This is a different concept from amps, which measure electric current, i.e. the "rate" at which electricity flows: to know how much power is being used by an electrical device (light bulb, refrigerator, etc) you need to know the Voltage (220 or 240 V in most parts of the world, but 110 or 115 in some) and multiply this by the current in amps. This gives you the power (in watts, which is the "metric" way of measuring power, as opposed to the British and American way). It is simple to convert watts to bhp (or vice versa), as 1 bhp = 746 Watts (or 0.746 Kw).
Example 1. Your car engine is capable of generating 200 bhp. You could also describe this as being capable of generating 149 Kw (200 x 0.746), and many foreign car manufacturers use this rather than bhp.
Example 2. Suppose you live in a country where the voltage is 240 V, and you have an electric heater which draws 10 amps. Your heater is consuming power (energy) at the rate of 240 x 10 = 2400 watts (i.e. 2.4 Kw). This is 2.4 / 0.746 = 3.2 bhp (but you would be thought very odd to rate an electric heater in this way - the whole world uses the metric system for this!)
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.
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.
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
To convert horsepower (HP) to amperes (A), you will also need to know the voltage at which the motor operates. The formula to calculate amperage from horsepower is: Amps = (HP x 746) / (Volts x Efficiency). Once you have the voltage and efficiency of the motor where the 10 HP is driven, you can use this formula to calculate the amperage.
You are thinking watts to horsepower, not amps to horsepower. Please restate the question.
To calculate horsepower, you can use the formula: Horsepower = (Volts x Amps x Efficiency) / 746. Using 110 volts and 15 amps, and assuming 90% efficiency, the formula would be: (110 x 15 x 0.9) / 746 = 1.49 horsepower.
To calculate horsepower, use the formula: Horsepower = (Voltage x Current x Efficiency) / 746 Given 110 volts and 7 amps: Horsepower = (110 x 7) / 746 Horsepower ≈ 1.03 hp
To convert amps to horsepower for a chainsaw, you also need to know the voltage of the chainsaw. Since power (in watts) = voltage × current (amps), horsepower can be calculated using the formula: 1 horsepower = 746 watts. You can then use this information to calculate the horsepower by converting watts to horsepower.
for 1 hp we cnt say the amps why because hp will mention the speed in never will differ but comparatively amps (load) will differ dip pends upon the voltage (380,220,440)W = V * I / I = W / V
You don't. The units measure different things.
To calculate the Run Load Amps (RLA) if it is not given, you can use the formula: RLA = Horsepower x 746 / Efficiency x Voltage x Power Factor x √3 x FLA, where FLA is the Full Load Amps. You need to know the motor's horsepower, efficiency, voltage, and power factor to determine the RLA. If these values are not known, you may need to contact the manufacturer or consult the motor's specifications.
To calculate horsepower you need the car's torque numbers. To find the horsepower, the formula HP=(RPM*T)/5252. The "HP" stands for "horse power", the "T" in the formula stands for "torque " and RPM stands for the RPM values. To calculate the horse power of an electric motor, you use the formula HP= (V*l*eff)/746. V=voltage, l=amps, and eff= efficiency.
At what voltage? If you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
1 horsepower = 746 watts, 1 watt = 1 volt x 1 amp => 20 Horsepower = 14,920 watts => 14,920 watts / 220 volts = 67.82 amps
To calculate amps in a circuit, use the formula: Amps Volts / Ohms. This formula helps determine the current flowing through a circuit based on the voltage and resistance present.
