Default Converting Logs

I was actually rather interested in the math content of an earlier thread, so if no one minds I would like to re-visit that topic.

The discussion was about converting logs from one base to another, and especially to base e. I wasn’t able to follow the example given, but have come up with the following:

If y = a^x, then log(y) = xlog(a)

So log(y) / log(a) = x

So to convert from log_10 to log_e I get

Log_10(y) / Log_10(e) = base e log of y

Is this correct?
