Measuring magnification

[Hellogreen]

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

I bought a magnifying glass 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.

Why do you need to rate the magnification of your magnifying glass? What did you buy it for and what do you want to do with it?

I guess people just rate them 2 times or 4 times but hey, you can always ask about their power when you buy them. ;)

Just a suggestion, perhaps you can conduct a simple experiment and compare the images you see roughly. But if you are interested in knowing their real value I'm afraid you have to read up!
