### Hp to volts Conversion Calculator:

Enter the horse power, current in amps, power factor between 0 to 1. By pressing the calculate button you can get the voltage values in Volts. You can choose DC, AC or AC single phase, AC three phase or Line to line and line to phase voltage for calculating.

### Hp to volts Calculation:

HP is the short form of horsepower. For converting HP to volts we have three sets of the formula for DC, AC single-phase and AC three-phase.

### Hp to DC volts calculation:

DC voltages V_{(V)} in volts is equal to 746 times of horsepower P_{(HP) }in HP divided by current in I_{(A)} in Amps. The DC volts formula will be

V_{(V)} = 746 x P_{(HP)} / I_{(A)} volts

**Note:** The voltage V_{(V)} can be measured between the positive to the negative terminal

__Example:__

A 1 HP DC motor has 1.7 Amps current flow, calculate the voltage across the positive and negative terminal.

DC Voltage = 746 x 1 / 1.7 = 438 Volts.

### Hp to AC single phase volts calculation:

AC Line to the neutral voltage V_{(V)} in volts is equal to 746 times of horsepower P_{(HP)} in HP divided by the multiplication of power factor and circulating current I_{(A)} in Amps.

The phase to neutral voltage V_{(V)} = 746 x P_{(HP)} / pf x I_{(A)} in Volts

**Note:** The AC voltage V_{(V)} can be measured between the Phase to the neutral terminal

__Example:__

A 10 HP AC single phase motor has 39 Amps current flow with 0.86 power factor, calculate the voltage across the phase to neutral terminal.

AC Voltage = 746*10 / (39*0.86) = 222.4 Volts.

### HP to Three phase volts calculation:

AC three phase voltage V_{(V)} in volts is equal to 746 times of the total power P_{(HP)} divided by three times of the multiplication of power factor and circulating current I_{(A)} in Amps.

The Line to neutral voltage V_{(V)} = 746 x P_{(HP)} / (3 x I_{(A)} x pf) in Volts

**Note:** The AC three phase voltage V_{(V)} can be measured between the Phase to neutral terminal

At the same time Line to line voltage V_{(V)} is equal to 746 times of the power P_{(HP)} in HP divided by root three times of the current I_{(A) }in Amps

The Line to Line Voltage V_{(V)} = 746 x P_{(HP)} / (√3 x pf x I_{(A)}) in Volts

**Note:** The AC voltage V_{(V)} can be measured between the Phase to Phase terminal

__Example:__

A 10 HP AC three phase motor has 0.85 power factor, 12 Amps current flow, calculate the voltage across the phase to phase terminal.

AC three phase Voltage =746*10 / (1.732*12*0.85) = 422.27 Volts
