Dear Sir,
Ampere to Horsepower::
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.
HP to KV::
1 Kw equals 1.36 hp. So, Kw x 1.36 = hp
KVA to HP:::
1 HP = 0.9325 kVA
1 KVA = 1/0.9325 HP
1000 KV to HP:::
British System:-
746W = 1 H.P.
1000W (1 kW) = (1000 / 746) H.P. = 1.34 H.P.
Metric System:-
735.5W = 1 H.P.
