What is 45 megaohms in microsiemens?

To convert 45 megaohms to microsiemens, first convert megaohms to ohms: 45 megaohms equals 45,000,000 ohms. The relationship between resistance (in ohms) and conductivity (in siemens) is given by the formula: conductivity (S) = 1/resistance (Ω). Therefore, 45 megaohms corresponds to a conductivity of approximately 0.0000222 siemens, or 22.2 microsiemens.
