## dBm to Watts Formula:

If you want to convert the power units from dBm into Watts then here’s the formula to convert dBm to Watts manually,

**$$ P(W)=1W \times \frac{10^{\frac{P(dBm)}{10}}{}}{1000} $$**

Where:

**P(W)**– Power in watts (W)**P(dBm)**– Power in decibel-milliwatts (dBm)

## How to Convert dBm to Watts?

Converting dBm to Watts might sound technical, but it's a straightforward process, using its formula you can easily convert dBm to Watts.

Now we will show you an example that helps you calculate dBm to Watts conversion. You can also try our dBm to Watts calculator for this purpose.

### Example:

Suppose you have a signal with a power level of 20 dBm, and you want to find out how many Watts that is equivalent to.

### Solution:

let's convert dBm to Watts using its formula:

$$ P(W)=1W \times \frac{10^{\frac{P(dBm)}{10}}{}}{1000} $$

Now put all the values into the dBm formula:

$$ P(W) = 1 \times \frac{10^{\frac{20}{10}}}{1000} $$

Calculate the exponent:

$$ P(W) = 1 \times \frac{10^{2}}{1000} $$

Calculate 10 to the power of 2:

$$ P(W) = 1 \times \frac{100}{1000} $$

Finally, divide by 1000 to get the power in Watts:

$$ P(W) = 0.1 \text{ Watts} $$

So, a signal with a power level of 20 dBm is equivalent to 0.1 Watts.

## FAQs:

### What is dBm?

dBm is the abbreviation of decibel milliwatts. It’s a unit used to measure the strength or power of signals, like Wi-Fi or cell phone signals. It helps us know how strong or weak a signal is, with higher numbers indicating stronger signals and lower numbers indicating weaker signals.

It's a way to measure signal strength and __efficiency__ in a more precise and standardized manner without getting into technical details.

### What is the dBm equivalent for 1 watt?

The dBm equivalent for 1 watt is **30 dBm**.

dBm is a unit of power measurement that is used in radio __frequency__, microwave, and fiber optic communications. It is a logarithmic scale, which means that each increase of 10 dBm represents a tenfold increase in power.

A power level of 0 dBm is equal to 1 milliwatt (mW). So, a power level of 30 dBm is equal to 1 watt.
