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.
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.
To convert amps and volts to horsepower (HP), you can use the formula: HP = (Volts × Amps) / 746. For 8 amps at 110 volts, the calculation would be (110 × 8) / 746, which equals approximately 0.88 HP.
ANSWER: I will assume the chainsaw is running off 115 volts and is single phase. The formula for this is: HP = VOLTS x Amps x Efficiency x Power Factor / 746 Lets say a single phase 115 volt AC Motor (the chainsaw) has an efficiency rating of 92%, and a power-factor of 80% (because it's inductive). Determine the horsepower if the amp load is 9 amps. HP = 115 x 9 x 0.92 x 0.80 / 746 = 1.021 Horsepower While you don't know the exact efficiency and power factor of your chainsaw I think this is close enough. Any size chainsaw is very dangerous.
To convert electrical power (in watts) to mechanical power (in horsepower), you typically need to take into account the efficiency of the system. However, to provide a rough estimate, you can use the formula: 1 horsepower is approximately equal to 746 watts. Therefore, 120 watts would be roughly 0.16 horsepower. Amps alone cannot be converted to horsepower without knowing the voltage across which the current is flowing.
To convert VA to amps, you can use the formula Amps = VA / Volts. In this case, Amps = 140 VA / 240 V = 0.5833 Amps.
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.
To convert amps and volts to horsepower (HP), you can use the formula: HP = (Volts × Amps) / 746. For 8 amps at 110 volts, the calculation would be (110 × 8) / 746, which equals approximately 0.88 HP.

Amps is amps be it DC or AC.
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.
