## How to convert kilowatts(KW) to amps(A)?

## kilowatts to amps calculation formula in DC

I=The current I in amps

P=the power P in kilowatts

V=the voltage V in volts

**I(A) = 1000 × P(in kW) / V(in volt)**

So that you can say that amps(A) are equal to 1000 times kilowatts(KW) divided by volts

**amps(A) = 1000 × kilowatts(in KW) / volts(V)**

or

**A(amps) = 1000 × kW / V(volts)**

**Let’s take one Example**

**Example#1**

Find out the current in amps(A) Where the power utilization is 20 kilowatts and the voltage supply in circuit is 23 volts.

P=20kw

V=23

I=1000*20/23

I=869.56amps

### kilowatts to amps calculation formula in AC single phase

I=The phase current I in amps

P=the real power P in kilowatts

PF=the power factor PF times

V=the RMS(root mean square) voltage V in volts:

**I = 1000 × P(power) / (PF × V(voltage) )**

So that definition is amps(A) are equal to 1000 times kilowatts(kw) divided by pf times volts.

**amps(A) = 1000 × kilowatts(kw) / (PF × volts(v))**

or

**A = 1000 × kW / (PF × V)**

**Let’s take one Example**

**Example#2**

Find out the current in amps(A) where the power utilization is 25 kilowatts, the pf is 0.8 and the RMS(root mean square) voltage supply is 230 volts.

P=25KW , V=230V , PF=.8

I = 1000 × 25kW / (0.8 × 230V) = 3.75A

I=1000*25/.8*230

I=25000/184

I=135.86amps

### kilowatts to amps calculation formula AC three phase

I=The phase current I in amps

P=the real power P in kilowatts

PF=the power factor PF times

VL-L=the line to line RMS voltage VL-L in volts:

**I = 1000 × P(power) / (√3 × PF × VL-L )**

So using above formula amps(A) are equal to 1000 times kilowatts(kw) divided by √3 times pf times volts.

**amps(A) = 1000 × kilowatts(KW) / (√3 × POWER FACTOR × volts)**

**OR**

**A = 1000 × kW / (√3 × PF × V)**

**OR**

**Kw=sqrt3*V*I*pf/100**

**Let’s take one Example**

**Example#3**

Find out the current in amps(A) where the power utilization is 0.55 kilowatts, the PF is 0.8 and the voltage supply in circuit is 120volts

I(amps) = 1000 × 0.55kW / (√3 × 0.8 × 120V) =3.307A

### How to convert kw to amps in three phase system with line to neutral voltage

**I(A) = 1000 × P(in kW) / (3 × Power factor × VL-N(V) )**

**OR**

**I=Kw*1000/3*V*pf**

I=average current in 3 phase system

pf=power factor

**Let’s take one example:**

**Example#4**

Find out the current in amps(A) where the power utilization is 0.55 kilowatts, the PF is 0.8 and the

voltage supply in circuit is 120volts.

I(amps) = 1000 × 0.55kW / (3 × 0.8 × 120V) =1.9A
