### Hp to amps Conversion Formula:

We calculate the flow of current from HP, we have three sets of the formula for DC, AC single-phase and AC three-phase.

**Note:** All we have calculated Line current only.

### Hp to DC amps calculation:

DC currents I_{(A)} in amps is equal to 746 times of horsepower P_{(HP) }in HP divided by voltage in V_{(V)} in Volts. The DC current in amp formula will be

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

**Note:** The current I_{(A)} in the amp can be measured at either positive or negative terminal.

__Example:__

Calculate the current flow through the 1.5 HP DC motor which has the potential difference between positive and negative terminal of 400V

DC Current = 746 x 1 / 400 = 1.865 Amps.

### Hp to AC single phase amps calculation:

Single-phase AC current I_{(A)} in amps is equal to 746 times of horsepower P_{(HP)} in HP divided by the product of power factor and phase to the neutral voltage V_{(V)} in volts.

AC single phase current I_{(A)} = 746 x P_{(HP)} / (pf x V_{(V)}) in Amps

**Note:** The single-phase AC current I_{(A)} can be measured through the phase side only.

__Example:__

A 10 HP AC single phase motor has 230 Volts of voltage flow with 0.86 power factor, calculate the current.

AC Current = 746*10 / (230*0.86) = 37.71 Amps.

### HP to Three phase amps calculation:

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

The phase current in amps I_{(A)} = 746 x P_{(HP)} / (3 x V_{(V)} x pf) in Amps

**Note:** The AC three-phase current I_{(A)} can be measured in phase side

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

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

**Note:** The AC current V_{(V)} can be measured in line side.

__Example:__

A 10 HP AC three-phase motor has 415 Volts of voltage with 0.86 power factor, calculate the line current.

AC three phase line Current =746*10 / (1.732*415*0.85) = 12.2 Amps.
