In engineering (in particular, in fiber optics), the logarithmic form of representing numbers is often used. It is convenient if the value sequentially passes through a series of points with input and output. And at each point, the output value is equal to the input value multiplied by a certain coefficient. For example, a laser diode has a power of -5dBm, a fiber has an attenuation factor of 0.3dB/km, and connectors have an attenuation factor of 0.15dB. Therefore, at the output of a 10-kilometer fiber, the radiation power will be (-5)-0.15-(0.3x10)-0.15=-8.3dBm. It would be much more unpleasant to consider this in linear terms. Therefore, transmitter powers and receiver sensitivities are often given directly in logarithmic terms (dBm) rather than linear values (mW).
I think that different schemes for bank deposits and other investments may also predispose in some cases to the use of logarithmic values. Is it so? Are logarithmic values used in finance?
