Volts to Amps Calculator
Use this free volts to amps calculator to convert voltage and power (watts) into current (amps). Ideal for electrical circuit calculations and quick conversions.
Quick Intro: Convert Volts to Amps
To convert volts to amps, you need to divide power (watts) by voltage. This is based on Ohm’s Law, where current equals power divided by voltage (I = P ÷ V). Our online calculator simplifies this conversion for DC and AC systems by factoring in voltage, power, and power factor where applicable.
Formula to Convert Volts to Amps
- DC: Amps = Watts ÷ Volts
- Single-Phase AC: Amps = Watts ÷ (Volts × PF)
- Three-Phase AC: Amps = Watts ÷ (√3 × Volts × PF)
