How to convert electric current in amps (A) to electric power in watts (W)?

amps to watts calculation formula in DC

P(W) = I(amps) × V(volts)

P=The power P in watts (W)
I=current I in amps (A)
V=the voltage V in volts (V)
So you can define watts are equivalent to amps times volts

watt(P) = amps(I) × volt(V)
or
W = A × V

Let take one Example
Example#1
Calculate the power utilization in watts(w) if the current is 5A and the voltage supply is 120V in a electrical circuit
Apply formula for the solution
P = 5A × 120V = 600W

amps to watts calculation formula in AC single phase

P=The real power P in watts (W)
PF=the power factor PF
I=the phase current I in amps (A)
V=the RMS voltage V in volts (V)

P(Watts) = PF × I(amps) × V(volts)

So you can define watts(w) are equivalent to the power factor times amps(I) times volts(V)

watt(p) = PF × amps(I) × volt(v)
or
W = PF × A × V

Let’s take one example
Example#2
Find out the power utilization in watts(W) if the power factor(PF) is 0.8 and the phase current is 5A and the RMS(Root mean square) voltage supply is 120V?
Apply formula for the solution
P = 0.8 × 5A × 120V = 480W

amps to watts calculation formula im AC three phase (amps to Watts calculation with line to line voltage)

P=The real power P in watts (W)
PF=the power factor PF times
I=the phase current I in amps (A)
VL-L=the  line to line RMS voltage VL-L in volts (V)

P(Watts) = √3 × Power Factor × I(amps) × VL-L(volts)

So using above formula you can define watts(W) are equal to √3 power factor(PF) times amps times volts(V):

watt(W) = √3 × PF × amps × volt(V)
or
W = √3 × PF × A × V
Let’s take one example

Example#3
Find out the power utilization in watts(W) If the power factor(PF) is 0.8 and the current is 5A and
the RMS(Root mean square) voltage supply is 120V?
Apply formula for the Solution
P = √3 × 0.8 × 5A × 120V = 831.36W

Online Watts calculation with line to neutral voltage

P=The real power P in watts (W)
PF=the power factor PF
I=the phase current I in amps (A)
VL-0=the  line to neutral RMS(Root mean square) voltage VL-0 in volts (V)

P(Watts) = 3 × PF × I(amps) × VL-0(volts)

So you can define watts(W) are equivalent to 3 times  PF times amps(I) times volts(V)

watt(W) = 3 × PF × amps(I) × volt(V)
or
W = 3 × PF × A × V
Let’s take one example

Example#4
Find out the power utilization in watts(W) If the power factor(PF) is 0.8 and the current is 5A and
the RMS(Root mean square) voltage supply is 120V?
Apply formula for the Solution
watt(W) = 3 × .8 × 5A × 120V=1440W

Using Above example you can easily perform below conversion
  • 1 amp = watts
  • 3 amps to watts
  • 15 amps to watts
  • 1 amp = watts 220v
  • 6 amps to watts 240V
  • 1 amp = watts 12v
  • Amps to watts calculator
  • 10 amps to watts 220V
  • 1 amp watts 240v 12 volt
  • 1.5 amps to watts
