How to Measure magnification

How can I see how strong a magnifying glass is?

I bought this magnifying glass <!-- m --><a class="postlink" href="http://www.liangdianup.com/inventory/189901.htm">http://www.liangdianup.com/inventory/189901.htm</a><!-- m --> and I want

to know how to test it to see how strong it 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.
