Watts and amps are two units that measure electrical power and current respectively.

They are essential for understanding how electricity works and how it can be used in various circuits and devices.

However, not all currents are the same.

There are two types of currents: direct current (DC) and alternating current (AC).

DC is the type of current that flows in one direction only, such as from a battery. AC is the type of current that changes direction periodically, such as from a wall outlet.

Both types have their pros and cons.

DC can be more efficient and stable, but AC can be easily transmitted over long distances and can be stepped up or down using transformers.

But what if you want to **convert watts (electrical power) to amps (electrical current)** at a fixed voltage?

Or what if you want to measure watts and amps using a device?

This is where you need to know how to convert watts to amps using a formula or a calculator, and how to measure them using a multimeter.

In this article, we will explain how to do these tasks step by step.

## How to Convert Watts to Amps

The formula for converting watts to amps is quite simple. **You just need to divide the power in watts by the voltage in volts**.

This will give you the current in amps.

However, this formula only works for DC appliances.

For AC appliances, you need to consider another factor called power factor.

Power factor is a ratio that indicates how efficiently an appliance uses electricity.

It ranges from 0 to 1, with 1 being the most efficient.

To convert watts to amps for AC appliances, you need to divide the power in watts by the power factor times the voltage in volts. This will give you the current in amps.

For example, if you have a 1000 W DC appliance connected to a 120 V circuit, you can calculate the current as follows:

Amps = 1000 W Ã· 120 V

Amps = 8.33 A

However, if you have a 1000 W AC appliance with a power factor of 0.8 connected to a 120 V circuit, you can calculate the current as follows:

Amps = Watts Ã· (Power Factor Ã— Volts)

Amps = 1000 W Ã· (0.8 Ã— 120 V)

Amps = 10.42 A

As you can see, the current is higher for the AC appliance because it uses electricity less efficiently.

## How to Convert Watts to Amps Using a Calculator?

If you don’t want to use a formula, you can also use an online calculator or an app to convert watts to amps easily and quickly.

There are many online calculators or apps that can perform the conversion for you, such as following:

All you need to do is enter the power in watts, the voltage in volts, and the power factor (if applicable), and the calculator or app will give you the current in amps.

You can also switch between DC and AC modes and choose different units of measurement.

### Here is an guide to use the online calculator

â€¢ Go to the Calculator section and select the DC or AC mode

â€¢ Enter the power in watts, the voltage in volts, and the power factor (if applicable)

â€¢ Click on the Calculate button and see the result in amps

## Other methods to convert Watts to Amps

Alternatively, you can also measure watts and amps using a multimeter. A multimeter is a device that can measure various electrical quantities, such as volts, ohms, etc.

To measure watts using a multimeter, you need to multiply the voltage reading by the current reading.

To measure amps using a multimeter, you need to connect it in series with the circuit or device.

Here is an example of how to measure watts and amps using a multimeter:

â€¢ Set the multimeter to measure voltage and connect it across the circuit or device

â€¢ Note down the voltage reading in volts

â€¢ Set the multimeter to measure current and connect it in series with the circuit or device

â€¢ Note down the current reading in amps

â€¢ Multiply the voltage reading by the current reading to get the power in watts

## Conclusion

In conclusion, watts and amps are two important units that measure electrical power and current respectively. To convert watts to amps, you need to divide the power in watts by the voltage in volts. For AC appliances, you also need to consider the power factor.

To measure watts and amps, you need to use a multimeter and multiply the voltage reading by the current reading.

By knowing how to convert and measure watts and amps, you can better understand how electricity works and how it can be used in various circuits and devices.
