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
To convert amps to volts, you need to know the system type (single-phase or three-phase) and power in watts. The basic formula is: Volts = Watts / Amps. For three-phase systems, use Volts = Watts / (√3 × Amps) for line-to-line voltage. This calculator simplifies the process by automating these formulas and providing instant results for accurate voltage values.
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
Amps to Voltage Calculator Overview
The Amps to Volts Calculator helps you determine the voltage in an electrical circuit based on current (amps) and power (watts). Whether you're working with a single-phase or three-phase system, this tool simplifies electrical conversions. Simply enter the current in amps and the power in watts, and the voltage will be calculated automatically using the proper formula for your system type. This calculator is ideal for electricians, engineers, students, or anyone involved in electrical design and troubleshooting. You can also switch between AC and DC systems and calculate values for different voltage types (line-to-line and line-to-neutral for three-phase). It eliminates manual calculations, saves time, and ensures accuracy.
Sample Amps to Voltage conversion table
| System Type | Watts | Amps | Volts |
