# Convert to voltage. Ohms, amps, watts to volts

 Please enter only two values and set unit type if available. Other must be empty: Current (I):    Amps (A) mAmps (mA) Resistance (R): Ohms (Ω) kOhms (kΩ) MOhms(MΩ)  Power (P):     Watts (W) kWatts (kW) Formulas and results: Voltage (V): V = P / I = 200 V

### Voltage calculations for various Current and Power. V = P / I
