Amps To Volts Calculator

Instantly convert amps to volts using our free calculator. Choose single or three-phase systems and input power to get accurate voltage values online.

Quick Intro: Convert Amps to Voltage

Formulas for Voltage

  • Single-phase: Volts = Watts ÷ Amps
  • 3-phase (Line-to-Line): Volts = Watts ÷ (√3 × Amps)
  • 3-phase (Line-to-Neutral): Volts = Watts ÷ (3 × Amps)
  • DC Circuit: Volts = Watts ÷ Amps

Frequently Asked Questions - Amps To Volts Calculator:

What is the formula to convert amps to volts?

Volts = Watts ÷ Amps. For 3-phase, divide by √3 × Amps.

Do I need to know power to calculate volts?

Yes, power in watts is necessary to calculate voltage from current.

What's the difference between AC and DC voltage?

AC voltage alternates direction; DC voltage flows in one direction.

What is line-to-line voltage in 3-phase?

Voltage between any two of the three phase conductors.

Can this calculator be used for DC circuits?

Yes, the formula Volts = Watts ÷ Amps works for DC as well.

Is there a difference in formula for 3-phase?

Yes, 3-phase uses √3 in the denominator for line-to-line voltage.

What is √3 and why is it used?

√3 (approx. 1.732) accounts for phase angle differences in 3-phase systems.

How accurate is this amps to volts calculator?

It provides accurate results if input values are correct.

Is line-to-neutral voltage lower than line-to-line?

Yes, it's lower by a factor of √3 in a balanced 3-phase system.

Can I embed this calculator on my site?

Yes, you can generate a widget using our embeddable tool.
