Does log scale have units?

This doesn’t appear to have any units at all. This suggests that logkm and logm are actually dimensionless numbers.

What is the unit of ln V?

ln(V) and ln(Vo) must also be dimensionless and unitless for the equation to balance. Dadface said: RC and t both have the dimensions of time and so the ratio t/RC is dimensionless (and unitless). ln(V) and ln(Vo) must also be dimensionless and unitless for the equation to balance.

What is log10 scale?

The Richter Scale – Earthquakes are measured on the Richter Scale, which is a base 10 logarithmic scale. This scale measures the magnitude of an earthquake, which is the amount of energy released by it. For every single increase on this scale, the magnitude is increased by a factor of 10.
