## Obtain Watts from Amps and Volts:

Insert the number of Amps (A) and Volts (V) below and click on Calculate to obtain Watts (W).
A
V
W
The formula is (A)*(V) = (W). For example, if you have a current of 2 A and a voltage of 5 V, the power is 2A * 5V = 10W.

This comes from the equation P = I * V. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

## Obtain Amps from Watts and Volts:

Insert the number of Watts (W) and Volts (V) below and click on Calculate to obtain Amps (A).
W
V
A
The formula is (W)/(V) =(A). For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A.

This comes from the equation I = P / V. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.

## To obtain Volts you need both Watts and Amps:

Insert the number of Watts (W) and Amps (A) below and click on Calculate to obtain Volts (V).
W
A
V
The formula is (W)/(A) =(V). For example, if you have a power of 10W with a current of 2A the voltage is 10W / 2A = 5V.

This comes from the equation V = P / I. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.
