From http://pewebdic2.cw.idm.fr/ :

1 if something is an order of magnitude greater or smaller than something else, it is ten times greater or smaller in size or amount
2 the scale of the size of something:
That was a problem but this crisis is of a different order of magnitude.

If someone says my books is two orders of magnitude more than yours, it means I have 100 times more than yours.

So in short,
1 order of magnitude = 10 times
2 orders of magnitude = 100 times
3 orders of magnitude = 1000 times
