Changing log base formula
WebThe famous "Richter Scale" uses this formula: M = log 10 A + B. Where A is the amplitude (in mm) measured by the Seismograph and B is a distance correction factor. Nowadays there are more complicated formulas, but they still use a logarithmic scale. Sound. Loudness is measured in Decibels (dB for short): Loudness in dB = 10 log 10 (p × 10 12) WebMar 6, 2024 · Changing the base formula, as the name suggests, is used to change the base of the logarithm. In this following step-by-step guide, you learn more about the change of base formula. You may have noticed that a scientific calculator only has “\(log\)” and “\(ln\)” buttons.
