The Volts to Watts Calculator is used to convert any RMS voltage value in V to the power in Watts (W), using the RMS voltage (V) and the system impedance Z (in ohms) value entered by the user. The calculator uses the following formula: 

Where, 

V - Represents the root–mean–square value of the electrical signal in Volts.
W – Electrical signal power in Watts (W)
Z- System impedance in ohms.

The Volts to Watts calculator helps to calculate the power in Watts from the RMS voltage value (V) by inputting the RMS voltage (in V) and system impedance Z (in ohms). The calculator quickly and accurately calculates Power (W) from RMS voltage (V) and impedance (Z). This calculator is a useful tool for engineers working in various electrical and electronic applications where electrical power calculations play a vital role in design, analysis, and optimization.
