This calculator helps convert electric current (amps) and power (watts) into voltage using the formula:
Formula:
V = P / IWelcome to the most accurate and user-friendly Amps to Volts Calculator online! Whether you're working on a home electrical project, learning electrical engineering, or just solving homework problems, this calculator helps you quickly convert amperes (amps) to volts using the appropriate formula based on the power system.
Amps (A) stand for amperes, which measure electric current โ the flow of electric charge.
Volts (V) measure electrical potential or pressure โ how much force pushes electrons through a circuit.
Think of it like water in a pipe: amps are the amount of water flowing, while volts are the pressure pushing the water through.
The formula to convert amps to volts depends on what other information you have. The most common scenario uses Ohm's Law or the Power Formula.
V = I ร R
V = P / I
If you have 2 amps of current and resistance of 10 ohms:
V = I ร R = 2 ร 10 = 20 Volts
If power = 100 watts and current = 5 amps:
V = P / I = 100 / 5 = 20 Volts
(Assuming Resistance = 10 Ohms)
| Current (Amps) | Voltage (Volts) |
|---|---|
| 1 A | 10 V |
| 2 A | 20 V |
| 3 A | 30 V |
| 4 A | 40 V |
| 5 A | 50 V |
| 6 A | 60 V |
| 7 A | 70 V |
| 8 A | 80 V |
| 9 A | 90 V |
| 10 A | 100 V |
The result updates instantly based on the formula selected.
If you're working with AC power, use this adjusted version of the formula:
V = P / (I ร PF)
P = 2000 watts, I = 10 amps, PF = 0.9
V = 2000 / (10 ร 0.9) = 222.22 Volts
To reverse the calculation:
I = V / R or I = P / V
A: Use Ohm's Law: V = I ร R, or Power formula: V = P / I.
A: Yes, if you know power in watts. Use: V = P / I
A: V = I ร R = 5 ร 10 = 50 volts
A: You must know either resistance or wattage to calculate volts.
function ampsToVolts(amps, resistance) {
return amps * resistance;
}
This is useful for developers building electrical calculators, apps, or embedded device UI.

Beyond simple homework problems, Amps to Volts conversions are a daily necessity in many industries:
Getting precise results when converting amps to volts requires good measurement practices:
V = P / (I ร PF).ฮV = I ร R_cable, then add to your conversion result.In industrial settings you often deal with three-phase power. Converting amps to volts in a three-phase circuit uses:
V_line = P_total / (โ3 ร I_line ร PF)
This formula ensures each phase delivers the correct voltage under load.
