Zoom in plzz

[xor83]

Recently I have bought Canon S3 IS. I am confuse with optical zoom while zooming to the end the display show some value like 90mm what is this “mm” means here before purchasing camera I have seen on many reviews that it supports 36 - 432 mm. what are the difference in these values. Is there any problem in my camera?

The 36-432 mm is the 35mm equivalent. That means that you would need a lens that size on a 35mm camera to get the same image. All these numbers are doing is converting your actual focal lenth into numbers that are more familiar to photographers since most people have shot with 35mm film in the past. Because of the small size of the image sensor in the S3, the ACTUAL focal lenght numbers are much smaller )6-72mm). I would say that there is nothing wrong with your camera.
