dBW or *decibel-watt* is a unit of power in decibel scale, referenced to 1 watt (W).

The power in decibel-watts (*P*_{(dBW)}) is equal to 10 times base 10 logarithm of the power in watts (*P*_{(W)}):

*P*_{(dBW)} = 10 ⋅ log_{10}( *P*_{(W)} / 1W)

The power in watts (*P*_{(W)}) is equal to 10 raised by the power in decibel-watts (*P*_{(dBW)}) divided by 10:

*P*_{(W)} = 1W ⋅ 10^{(P}(dBW)^{/ 10)}

1 watt is equal to 0 dBW:

1W = 0dBW

1 milliwatt is equal to -30dBW:

1mW = 0.001W = -30dBW

How to convert power in dBW to watts (W).

The power in watts (*P*_{(W)}) is equal to 10 raised by the power in dBW (*P*_{(dBW)}) divided by 10:

*P*_{(W)} = 1W ⋅ 10^{(P}(dBW)^{/ 10)}

For example: what is the power in watts for power consumption of 20dBW?

Solution:

*P*_{(W)} = 1W ⋅ 10^{(20dBW} ^{/ 10)} = 100W

How to convert power in watts (W) to dBW.

The power in dBW is equal to the base 10 logarithm of the power in watts (W):

*P*_{(dBW)} = 10 ⋅ log_{10}( *P*_{(W)} / 1W)

For example: what is the power in dBW for power consumption of 100W?

Solution:

*P*_{(dBW)} = 10 ⋅ log_{10}( 100W / 1W) = 20dBW

How to convert power in dBW to dBm.

The power in dBm is equal to the base 10 logarithm of the power in watts (W):

*P*_{(dBm)} = *P*_{(dBW)} + 30

For example: what is the power in dBm for power consumption of 20dBW?

Solution:

*P*_{(dBm)} = 20dBW + 30 = 50dBm

How to convert power in dBm to dBW.

The power in dBW (*P*_{(dBW)}) is equal to 10 raised
by the power in dBm (*P*_{(dBm)}) divided by 10:

*P*_{(dBW)} = *P*_{(dBm)} - 30

For example: what is the power in watts for power consumption of 40dBm?

Solution:

*P*_{(dBW)} = 40dBm - 30 = 10dBW
