The dBm (decibel-milliwatts) conversion calculator is a tool that allows you to easily convert between decibel-milliwatts (dBm), milliwatts, watts, and decibel-watts (dBW). Simply enter a value in one of the fields and click the “Convert” button next to it to see the corresponding values in the other fields. You can also use the “Reset” button to clear all input fields. This calculator is useful for engineers, technicians, and anyone who works with wireless communication systems and wants to quickly and accurately convert power measurements.

dBm to Watt, mW, dBW Conversion table
The formula for this conversion is:
P(dBm) = 10 ⋅ log10(P(mW) / 1mW)
where P(dBm) is the power in dBm and P(mW) is the power in milliwatts.
For example, if you have a power consumption of 200 mW, the power in dBm would be:
P (dBm) = 10 ⋅ log10 (200 mW / 1 mW) = 23.0102999 dBm

To convert from dBm to mW, you can use the following formula:
P(mW) = 1mW ⋅ 10(P(dBm) / 10)
where P(mW) is the power in milliwatts and P(dBm) is the power in dBm.
For instance, if you have a power consumption of 60 dBm, the power in mW would be:
P (mW) = 1mW ⋅ 10(60dBm / 10) = 1000000 mW

The formula for this conversion is:
P(dBm) = 10 ⋅ log10( P(W) / 1W) + 30
where P(dBm) is the power in dBm and P(W) is the power in watts.
For example, if you have a power consumption of 200 W, the power in dBm would be:
P (dBm) = 10 ⋅ log10( 200W / 1W ) + 30 = 53.010299956 dBm
Watts to dBm conversion calculator ►
To convert from dBm to W, you can use the following formula:
P (W) = 1W ⋅ 10((P(dBm) – 30) / 10)
where P (W) is the power in watts and P (dBm) is the power in dBm.
For instance, if you have a power consumption of 40dBm, the power in W would be:
P (W) = 1W ⋅ 10((40dBm – 30) / 10) = 10 W

Moving on to dBW and dBm, the conversion formula is:
P(dBm) = P(dBW) + 30
where P(dBm) is the power in dBm and P(dBW) is the power in dBW.
For example, if you have a power consumption of 30 dBW, the power in dBm would be:
P (dBm) = 30 dBW + 30 = 60 dBm
To convert from dBm to dBW, you can use the following formula:
P(dBW) = P(dBm) – 30
where P (dBW) is the power in dBW and P (dBm) is the power in dBm.
For instance, if you have a power consumption of 70dBm, the power in dBW would be:
P (dBW) = 70dBm – 30 = 40 dBW
