How to Measure magnification
How can I see how strong a magnifying glass is?

I hear a lot of people talk about
magnifying and how strong the magnification is, but I would like to know the true
magnification of my magnifying glass. I have a few of them and some seem stronger then
others. How can I rate these? How can I pin a correct number on mine? How do the companies
that make these come up with these numbers.

Read the wikipedia entry, it describes how magnification is "measured" by distance to best focus. It doesn't sount too precise.
