Watts to dBm conversion
A
Watts to dBm Conversion Calculator
Enter the power in watts and press the Convert button:
The power P(dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P(W) in watts (W) divided by 1 watt (W):
P(dBm) = 10 ⋅ log10( 1000 ⋅ P(W) / 1W) = 10 ⋅ log10( P(W) / 1W) + 30
so
1W = 30dBm
Example
Convert 20 watts to dBm:
P(dBm) = 10 ⋅ log10(1000⋅20W) = 43.0103dBm
