dBW definition
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 ⋅ log10( 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 dBW to Watt
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 Watt to dBW
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 ⋅ log10( P(W) / 1W)
For example: what is the power in dBW for power consumption of 100W?
Solution:
P(dBW) = 10 ⋅ log10( 100W / 1W) = 20dBW
How to convert dBW to dBm
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 dBm to dBW
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
