WebThis audio tools provides a quick and convenient means to convert between them. dBV refers to a voltage magnitude referenced to 1 volt, while dBu is referenced to 0.775 volts. … WebDec 8, 2024 · The formula for dBm is. d B m = 10 ∗ l o g ( P 1 / P 0) where P0 = 1mW. so. + 13 d B m = 20 m W. If I convert this to a voltage using the formula P = V r m s 2 / R where R = 50 ohm, I find that. V r m s 2 = 20 m W ∗ 50 o h m = 1000 m V. V r m s = 31.62 m V. Now if I solve the equation a different way I get a different result.
