🔌 Amps to Volts Calculator
Want to know how to convert amps to volts?
It’s simple: volts = watts ÷ amps. If you already know the power in watts and the current in amps, this calculator instantly gives you the voltage. For example, a 100-watt device running at 5 amps equals 20 volts.
Our Amps to Volts Converter is designed for electricians, students, engineers, and anyone working with electrical systems. Instead of manual calculations, just enter the values, and the tool instantly provides accurate voltage results — whether for household appliances, solar panels, batteries, or industrial equipment.
What is an Amps to Volts Converter?
An Amps to Volts Converter is a simple calculator that helps you determine voltage (V) when you know the current (A) and power (W).
Formula:
Volts (V) = Watts (W) ÷ Amps (A)
Example:
If a fan uses 120 W at 2 A, the voltage is 60 V.
This conversion is essential in solar power systems, battery setups, and electronic circuits, where knowing the correct voltage ensures safety and efficiency.
How to Use the Amps to Volts Calculator
Using our tool is quick and beginner-friendly:
Enter the current in amps (A).
Enter the power in watts (W).
Click Convert.
Instantly see the voltage in volts (V).
💡 Pro Tip: For AC systems, include the power factor (PF) if available for more accurate results.

FAQs:
Q1: How do I convert amps to volts?
To calculate volts from amps and watts, simply use the formula:
Volts = Watts ÷ Amps
You must know the power rating in watts to calculate.
Q2: Can I convert amps to volts without watts?
No. Voltage depends on both current (amps) and power (watts). Without knowing the power, the conversion isn’t possible.
Q3: Why is amps to volts conversion important?
It ensures the safe operation of electrical devices, helps with correct wire sizing, and avoids overloads in circuits, especially in solar systems and batteries.
Q4: Does the power factor affect conversion?
Yes, for AC loads, actual voltage depends on both power and power factor (PF). Our calculator supports PF input for more accurate results.
Final Thoughts:
The Amps to Volts Converter helps you quickly and accurately calculate voltage when you know amps and watts. It’s essential for electricians, engineers, students, and anyone working with electrical circuits or solar power systems.
Now, you can instantly convert amps to volts, saving time and ensuring accurate results for your projects.
