Are you sure you're looking at the units of the entire argument and not just one part? You can't have something like:. But you can have. You can fwsnort log units have something like:. Alright, I've found the seventh edition of the book and, if the equation here is the fwsnort log units you are talking about, then-yes, in the form he has it written, it is the log of a number with units, but just rearanging:. The important thing is that it doesn't matter what units you express "k" in, you'll just get "A" in those same units. What you want never to see is an equation like:. With an equation like that, your answer will always depend on the units. If you measure T in Kelvin, then at K, k is 0 because you have sin of an integer times pi. You don't end up with contradictions like these in the equation he gives. If you look at his graph, he has ln K on one axis. Personally I would not write it like this. Often you'll see authors write something like:. Last edited: Jan 8, The log of, say, some number of joules has units of "log joules. Of course you can. Whether that is then a meaningful quantity in itself is another matter entirely. If you indeed 'couldn't' take logs of numbers with units then fwsnort log units is the point of a log-log graph? Logarithms of numbers are useful as a method to treat data. Sometimes powers of numbers are useful as a method fwsnort log units treat data. Logarithms or powers often allow us to give an easy or easier description to numerical relationships. Recall, someone mentioned log-log graphs, and semi-log graphs. I'm not denying the usefulness of logs, just saying that I have never encountered a situation where it was useful to use logs with units.
