# A to W – Amperes to Watts – online electrical calculator

Enter the amperage in A (Amps):

Enter voltage in V (Volts):

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

Power in Watts is:

0.00W

## How to calculate the power in W, if we know the amperage?

You can calculate using the formula:

P = I х U, where

I is the current in amperes (A);

P is the power in Watts (W);

U is the voltage in volts (V).

Thus, to get Watts from Amperes, you need to multiply the amperes by the voltage in volts.

For example:

Convert 60 Amps to Watts if the voltage is 120 V:

P = I х U = 60*120 = 7200 W.

Convert 60 Amps to Watts if the voltage is 230 V:

P = I х U = 60*230 = 13800 W.

Convert 72 Amps to Watts if the voltage is 120 V:

P = I х U = 72*120 = 8640 W.

Convert 72 Amps to Watts if the voltage is 230 V:

P = I х U = 72*230 = 16560 W.

Convert 100 Amps to Watts if the voltage is 120 V:

P = I х U = 100*120 = 12000 W.

Convert 200 Amps to Watts if the voltage is 120 V:

P = I х U = 200*120 = 24000 W.
