Milliamps to Volts Calculator

Converting milliamps (mA) to volts (V) requires knowledge of resistance (R) in ohms (Ω) using Ohm’s law: V = I x R. Without resistance, you can’t directly convert mA to V. Voltage depends on both current and resistance. To determine voltage, you need the value of resistance in the circuit where the current flows.
