Conversions of power levels between W, dBW and dBm.

Enter one value (either in dBW, dBm or W) and click the "Convert" button next to it to compute the two other values.

	Power:
P =		dBm
P =		W
P =		dBW

Calculations are based on the following formulas:

• P_(dBm)=10·log₁₀(P_(W) / 0.001) = P_(dBW) + 30 , power level relative to 1 milliwatt;
• P_(dBW)=10·log₁₀(P_(W) / 1) = P_(dBm) - 30 , power level relative to 1 watt;
• P_(W)=0.001·10^(P_(dBm)/10), power in watts.
