Zoom to wrong point

Question

I have a form for users to enter latitude/longtitude and when sumitted, the map would centerAndZoom to the point, but the result is not what I thought would be.
Here're steps I take:
Create a point with lon/lat which, in turn, is converted to a point of webmercator using the following
point = webMercatorUtils.geographicToWebMercator(point) before setting it to a query.geometry.
Somehow, the location of point is calcualted way off.  Then I tried to create an extent around the point of webmercator, and it didn't work either.
Please help. 
Thanks.

You don't have to change how your users enter the lat/long information. Just have your users enter the lat/long as DMS and then before creating a JS API location point, convert the DMS to decimal degrees using a method such as this.

EDIT: Whoops. I now see that you say that your users can't offer this level of precision. That's going to be a problem because it's that precision that provides the true (or "better") accuracy of the point's location.

Thanks. My users want to enter decimal or degree at their choice. Of course, the simplest they would enter, say, 46, 93 I treat it as decimal. As for dms, I did this:
        lat = parseFloat(latlon[0]) + parseFloat(latlon[1])/60.0 + parseFloat(latlon[2])/3600.0 
 lon = -(parseFloat(latlon[3]) + parseFloat(latlon[4])/60.0 + parseFloat(latlon[5])/3600.0) ;

I'm new in GIS field. Not sure what's going on.
