Amps to Watts
How to Calculate
Amps to Watts using Volts
The interplay between electrical power, current, and voltage is crucial for efficient energy use. To convert from amperes (A), which measures electric current, to watts (W), which measures electrical power, use this formula:
Watts (W) = Amperes (A) × Volts (V)
- Identify the Amperage: Determine the current flowing through the electrical device or system, measured in amperes (A).
- Know the Voltage: Establish the voltage at which the electrical system operates, measured in volts (V).
- Calculate the Wattage: Multiply the amperage by the voltage using the formula W = A × V.
Note: This formula works well for resistive loads. For inductive or capacitive loads, you may need to consider additional factors like the power factor.

Watts to Amps using Volts
Electrical power, current, and voltage are interrelated components in any electrical system. When you need to convert electrical power (measured in watts, W) to electric current (measured in amperes, A), you can use the following formula:
Amperes (A) = Watts (W) / Volts (V)
- Identify the Wattage: Determine the power consumption of the electrical device or system, measured in watts (W).
- Know the Voltage: Establish the voltage at which the electrical system operates, measured in volts (V).
- Calculate the Amperage: Divide the wattage by the voltage using the formula A = W / V.
Note: This formula is generally applicable to resistive loads. For inductive loads, factors such as the power factor may also need to be considered.
