# How do you convert amperes and volts to watts?

Converting amperes to watts is quite simple. To do this, you do not only need the current in amperes but also the voltage in volts. You can then multiply these 2 numbers by each other to get the power in watts. Suppose your LED strip light works on 12 volts and uses 2.5 amperes, then the power is 12 × 2.5 = 30 watts. You can also use the handy tool below to convert amps to watts.

## How do you convert watts and volts to amperes?

Besides converting amperes and volts to watts, it is of course also possible to convert watts and volts back to amperes. You can do this by dividing the power in watts by the voltage in volts.

## What is voltage in volts?

Voltage indicates the electric potential difference, or the difference in potential energy between 2 points (often + and -). It indicates how much energy is carried by the electrons flowing through a device. The unit corresponding to this is the volt with the symbol V. This unit is named after the Italian physicist Alessandro Volta.

## What is current in amperes?

Amperes indicate the electric current. This is the amount of electrons flowing through a device. Ampere is abbreviated to A and is named after the French physicist André-Marie Ampère.

## What is the difference between voltage in volts and current in amperes?

The difference is that the current in amperes indicates how many electrons are flowing through a device while the voltage in volts indicates how much energy each of these electrons carries. A nice analogy for this is that of water. Here, the current is then comparable to the flow rate and the voltage to the pressure.

## What is power in watts?

Power indicates energy per unit of time and is often used to indicate the energy consumption of a device. Power is indicated in watts, which is also abbreviated to W. 1 watt thereby equals 1 joule per second. With electrical energy, as you could read in the introduction, power can be calculated by multiplying the amount of amperes by the amount of volts. The unit watt is named after the Scottish engineer James Watt.
