Pentadecimal notation?

While looking something up in an appendix of a textbook on engineering, I found this table. See if you can find the odd ones out.


Answer: Silver and tin have resistances simplified using a rather odd form of scientific notation. Bonus points if you noticed that tin’s “resistance” is so high that it is an insulator instead of a conductor!

Fortunately for the student, all three errors are simple in that we can easily tell what the correct values are. How they got this way is a mystery though.
