looking at magnifying lamps and i want to know what magnification it provides and they are listed by diopters

The power of a magnifying glass is generally given as 10/f, where f is focal length in inches. Diopter = 1/f, where f is focal length in meters. So conversion is M = D/4, approximately.

A dioptre is 1 over the focal length in metres.
From thos and the distance to the object and screen you can work out the magnification.

The definition of a dioper is very interesting it supposes to measure the strenght of the lens + or minus. It in terms of an inverse meter.
The Interesting thing is that the electic field is measured by the same way its an inverse distance.

It's the inverse of the focal length and is a measure of the strength of the lens.

D=1/f where f is focal length
