How do I compare zoom between point&shoot and DSLR camera?

Question by Robert Magrino: How do I compare zoom between point&shoot and DSLR camera?
I want to buy a camera with really good quality and very high zoom, I see a lot of point&shoot cameras that specify their zoom level, like some new models now indicate 20x zoom.
However, how would that compare to a dslr camera if I buy a telephoto lens or something,
how do I know if the dslr and lens have better than 20x zoom?

Most cameras now show the focal length in 35mm equivalents. If I take my old compact as an example then:-

It had a 10x zoom. The wide angle lens on this camera started at 25mm. That means simply the "zoom" was 25-250mm in equivalent terms as 25x10=250.

My DSLR lenses on the otherhand are:

18-55mm = 3x
50mm = 0x
70-300mm = 4.3x

Although the crop factor changes the values slightly in 35mm terms (18-55 becomes a 28-80 approx) the 3x "zoom" stays the same.

I think one of the biggest zooms on DSLR is the Tamron 15x 18-270mm
