Example: An air conditioner is powered by 800 Watts. How many Amps is that? It’s 5 Amps.

To convert electrical power to electrical current (Watts to Amps), we need to use the electrical power equation:

**P = I*V**

where:

- P is electrical power, measured in Watts (W)
- I is electrical current or amperage, measured in Amps (A).
- V is electrical potential or voltage, measured in Volts (V). The standard voltage for the majority of electrical devices is 110-120V and upgraded voltage powerful electric devices use is 220V.

Using this equation, we can convert watts directly to amps, if we know the voltage.

## Watts To Amps Calculator (W to A)

Here you can easily convert watts to amps using this calculator:

In order to demonstrate how watts can be converted to amps, we solved a few examples of how many amps is 500 watts, 1000 watts, and 3000 watts. In the end, you will also find a watts-to-amps table at 120V electric potential.

Here’s a quick useful piece of info:

*How many watts make an amp?*

At 120V, 120 watts make 1 amp.

At 240V, 240 watts make 1 amp.

With that in mind, let’s look at the 3 examples:

### Example 1: How Many Amps Is 500 Watts?

Let’s say we have a 500W air conditioner plug into 120 V voltage.

Here is how we can calculate how many amps is 500W:

**I = P/V**

If we input the P = 500 Watts and V = 120 Volts, we get:

**I = 500 Watts/120 Volt = 4.17 Amps**

In short, 500 Watts equals 4.17 Amps.

### Example 2: How Many Amps Is 1000 Watts?

If we repeat the exercise and ask ourselves how many Amps equals 1000 Watts we get:

**I = 1000 Watts/120 Volt = 8.33 Amps**

We see that a 1000 W device draws twice as many Amps as 500 W device.

### Example 3: 3000 Watts Equals How Many Amps?

3000 Watt devices can be plugin in 120V or into 220V. In cases with higher wattage, it’s not unusual to use a higher 220 voltage. This is designed to reduce the amperage.

For example, 3000 Watt equals to:

- 25 Amps, if you use 120 V.
- 13.64 Amps, if you use 220 V.

For 25 Amps, for example, you would already need an amp breaker. But if you plug such a device into 220 V, the current that is generated is only 13.64 Amps (there is no need for amp breakers).

**Example:** Bigger multi-zone mini-split units usually need amp breakers. You can check 2-zone, 3-zone, 4-zone, and 5-zone mini-split system to see how many amps they run on.
