Watts are watts ... and you're burning fossil fuels to make them watts ... what is this cable doing other than making carbon pollution? ...
Watt
Watts to amps calculator
Watts to amps (A) conversion calculator
(DC)
DC watts to amps calculation
The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):
I(A) = P(W) / V(V)
AC single phase watts to amps calculation
The phase current I in amps (A) is equal to the power P in watts (W), divided by the power factor PF times the RMS voltage V in volts (V):
I(A) = P(W) / (PF × V(V))
The power factor of resistive impedance load is equal to 1.
AC three phase watts to amps calculation
Calculation with line to line voltage
The phase current I in amps (A) is equal to the power P in watts (W), divided by square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V):
I(A) = P(W) / (√3 × PF × VL-L(V) )
The power factor of resistive impedance load is equal to 1.
Calculation with line to neutral voltage
The phase current I in amps (A) is equal to the power P in watts (W), divided by 3 times the power factor PF times the line to neutral RMS voltage VL-N in volts (V):
I(A) = P(W) / (3 × PF × VL-N(V) )
