### Amps to hp Conversion Calculator.

Enter the voltage, current and power factor.

### DC Amps to HP Calculation:

DC Horsepower P_{(HP)} is equal to 0.00134 times of dc voltage V_{(V)} in volts and dc current I_{(A)}.

P_{(HP)} = 0.00134 x V_{(V)} x I_{(A)}

__Example: __

Calculate the HP rating of the DC motor which has rated voltage of 400V and rated current of 215A.

HP = 0.00134 x 400 x 215 = 115 Hp

The motor HP rating is 115 Hp.

### AC Single Phase Amps to HP conversion Formula

For AC single phase power P_{(HP)} is equal to 0.00134 times of voltage V_{(V)} in volts, Current I_{(A)} in amps and power factor.

Single phase power P_{(HP)} = 0.00134 x V_{(V)} x I_{(A) }x pf

__Example: __

What would be the Hp rating of the motor which has rated input AC voltage of 230V and rated current of 3.8 Amps with 0.86 pf.

HP = 0.00134 x 230 x 3.8 x 0.86= 1 Hp

The Single phase motor capacity is 1 HP. By revising this calculation, 1 HP single phase motor takes 3.8 Amps.

### AC 3 phase Amps to HP conversion Formula

3 phase power P_{(HP)} is equal to 0.00402 times of current I_{(A)}, Line to the neutral voltage V_{(L-N)} in volts, power factor pf.

3 phase power in HP P_{(HP)} = 0.00402 x I_{(A)} x V_{(L-N)} x pf

While considering Line to line voltage, the three-phase power in HP will be

3 phase power P_{(HP)} = 0.00232 x I_{(A)} x V_{(L-L)} x pf

__Example: __

Find the HP rating of the 3 phase induction motor. The following nameplate details are line to line voltage 415 V, 1.3 Amps & 0.86 power factor.

HP = 0.00232 x 415 x 1.3 x 0.86= 1 Hp

The 3 phase motor capacity is 1 HP. By revising this calculation, 1 HP three phase induction motor takes 1.3 Amps.
