Enter the electric power **in W (Watts**):

Enter the voltage **in V (Volts):**

*(the most common voltage standard is 230 and 120 volts)*

Current **in A (Amps)** is:

## How to calculate the current in amperes if the power and voltage are known?

Amperes are determined by dividing Watts by Volts.

* I = P / U*, where

* I* is the current in amperes (A);

* P* is the power in Watts (W);

* U* is the voltage in volts (V).

For example:

Convert 3500 Watts to Amps if the voltage is 120 V:

I = P/V=3500 / 120 =29,16 A

Convert 3500 Watts to Amps if the voltage is 230 V:

I = P/V=3500 / 230 =15,22 A

Convert 1800 Watts to Amps if the voltage is 120 V:

I = P/V=1800 / 120 =15 A

Convert 1800 Watts to Amps if the voltage is 230 V:

I = P/V=1800 / 230 =7,83 A

Convert 150 Watts to Amps if the voltage is 120 V:

I = P/V=150 / 120 = 1,25 A

Convert 150 Watts to Amps if the voltage is 230 V:

I = P/V=150 / 230 =0,65 A
