Watt to volts conversion Formula (W to V)

As you know, Watt is the unit of Power and it is denoted by P(W); Volts is the SI unit of Voltage and it is denoted by V(V); Ampere is the SI unit of current and the same denoted by I(A);

  • The DC volts is equal to watt divided by the current for DC circuits
  • The Single phase AC volts is equal to Watt divided by the multiplication of current and Voltage.
  • Three-phase AC volts is equal to Watt divided by root three times of multiplication of current and power factor.

From the above relation, we can easily write the formula as follow,

DC volts V(V) = P(W) / I(A)

Single-phase Volts formula:

V(V) = P(W) / (PF × I(A) )

Three-phase Line to Line Volts formula: 

VL-L(V) = P(W) / (3 × PF × I(A) )
P(W) / (1.732 × PF × I(A) )

Three-phase Line to neutral Volts formula:

VL-N(V) = P(W) / (3 × PF × I(A))
