Amps or A = Ampere is a unit for measuring electric intensity (I). Horsepower (= HP) is a unit for measuring the power (P) of an engine
So for example: P=200 HP and I=5.2 A
Those two are totally different and irrelevant to each other.
----------------------------------------------------
Not entirely true. Amps are a factor in calculating power, and so can be used to determine horsepower, but only when other factors are present.
Given other factors, you can find the horsepower. The easiest way is to determine watts by multiplying amps X volts. Next multiply watts by .00134 and you have horsepower.
If: amps (A)= 20 and volts (V)=120 then
A X V =2400 watts (W)
2400 watts X .00134 = 3.216 horsepower
--------------------------------------
To add a further wrinkle:
Horsepower is a measurement of OUTPUT power
Amps generally refers to the flow of current (not intensity as stated above - that is voltage) which is an INPUT of an electric motor
So to accurately compute how much horsepower an electric motor will PRODUCE you need to know the efficiency of that motor. Electric motors tend to be very efficient but not quite 100%.
So, multiply efficiency by the theoretical hp using the formula above to get your final answer.
<<<<>>>>
Horsepower formulas;
Single phase HP = I x E x %eff x pf/746 (%eff = efficiency of the motor), (pf = power factor)
Three phase HP = I x E x 1.73 x %eff x pf/746 (%eff = efficiency of the motor), (pf = power factor)
Comment
What none of the above answers directly point out that horsepower is simply the Imperial Unit of measurement for power, in the same way that the watt is the SI unit for power.
746 watts equals one h.p. Multiply the number of h.p. times 746 and divide by the voltage. That will give you amps.
You need to know the voltage as well before the conversion can be made.
However on a 240 v system, a 1-HP motor should be allowed 7 amps in calculating the wire size etc.
You can't because they are not equivalent. To find the HP you must find the watts, which is volts times amps, times the power factor. Then 746 watts is 1 HP.
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.
one ton is equal to 4.71 horsepower.
To convert amps into watts a voltage is needed. Watts = Amps x Volts.
1 Amps = 1000 miliamps 0.01 Amps = X x= 0.01 X 1000 = 10 miliamps
15 amps X 415volts = 6225watts or 6.225Kw
You don't. The units measure different things.
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 are thinking watts to horsepower, not amps to horsepower. Please restate the question.
4.3 amps
Amps is amps be it DC or AC.
HP does not directly relate to cc
Please note that horsepower and amperes measure different things, so you can't just convert them directly. Convert the horsepower to watts. Then you can divide by the voltage used in your region - usually that's around 110 volts, or 220 volts, depending on the region - to get the amperes. This formula is correct for DC, and approximately correct for AC (in most common cases).
1 horsepower = 0.745699872 kilowatts you would convert it when you want a metric measurement for horsepower an example 400 horsepower(mechanical) = 298.2799 kilowatt
Watts are the product of amps x volts.
one ton is equal to 4.71 horsepower.
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.
