DC amps to kilowatts Calculation
Multiply of Amps(i) and Volt (v) is equal to The Power p(kW) is divided by 1000
or
The multiplication of amps and volt for Dc supply is equal to watt ie if 1 Ampere is taken with 12V volt dc then watt will be 12W.
DC amps to watts Formula is :
DC amps to kilowatts Formula is :
DC amps to milliwatts Formula is :

DC amps to kilowatts Examples | |
(1) let’s find the kilowatts of power for a circuit with 6 amps of current at 120 volts
Power = Current × Voltage ÷ 1000 |
(2) let’s find the kilowatts of power for a circuit with 6 amps of current at 240 volts
Power = Current × Voltage ÷ 1000 |
AC single phase amps to kilowatts Calculation

The power P in kilowatts (kW) is Multiply of Power Factor(PF), Amps(I) and Volt(V) divide by 1000.
or
The power P in watts (W), is equal to Multiply of Power Factor(PF), Amps(I) and Volt(V).
AC single phase amps to watts Formula is :
AC single phase amps to kilowatts Formula is :
AC single phase amps to milliwatts Formula is :
AC single phase amps to kilowatts Example | |
(1) let’s find the kilowatts of power for a single phase circuit with 6 amps of current at 120 volts and 0.5 Power Factor (PF)
Power = PF × Current × Voltage ÷ 1000 |
(2) let’s find the kilowatts of power for a single phase circuit with 6 amps of current at 240 volts and 0.5 Power Factor (PF)
Power = PF × Current × Voltage ÷ 1000 |
AC three phase amps to kilowatts Calculation

there are two types for three phase amps to kilowatts Calculation.
- line to line voltage
- line to neutral voltage
Calculation with line to line Voltage

The power P in kilowatts (kW) is equal to square root of 3 times the power factor (PF) amps (A), volts (V) divided by 1000 :
or
The power P in kilowatts (W) is equal to square root of 3 times the power factor (PF) amps (A), volts (V)

AC three phase amps to watts Formula is (L-L Voltage) :
AC three phase amps to kilowatts Formula is (L-L Voltage) :
AC three phase amps to milliwatts Formula is (L-L Voltage) :
Calculation with line to neutral Voltage
Multiply of 3 times the power factor (PF) amps (A) and volts (line) (V) divided by 1000, is equal to the power p in kilowatts(kW)
or
Multiply of 3 times the power factor (PF) amps (A) and volts (natural ) (V), is equal to the power p in watts(W)
AC three phase amps to watts Formula is (L-N Voltage) :
AC three phase amps to kilowatts Formula is (L-N Voltage) :
AC three phase amps to milliwatts Formula is (L-N Voltage) :
AC three phase amps to kilowatts Example | |
(1) let’s find the kilowatts of power for a three phase circuit with 6 amps of current at 120 volts (line to line) and 1 Power Factor (PF) Power = √3 × PF × Current × Voltage ÷ 1000 |
(1) let’s find the kilowatts of power for a three phase circuit with 6 amps of current at 120 volts (line to Neutral) and 1 Power Factor (PF) Power = 3 × PF × Current × Voltage ÷ 1000 |
So let’s some typical power factor values. the noted thing in these values that if you want a accurate calculation so you must don’t use these.
Typical PF (Power Factor) Values
No. | Device | Typical Power Factor Values |
1. | Induction motor no load | 0.35 |
2. | Induction motor full load | 0.85 |
3. | Synchronous motor | 0.9 |
4. | Fluorescent lamp | 0.95 |
5. | Resistive load | 1.00 |
6. | Incandescent lamp | 1.00 |
7. | Resistive oven | 1.00 |
