The Clipping graphic actually uses the native units of layer, so no conversion into meters is needed. The formula works for all projections.</SPAN><BR /><BR /><SPAN>Thanks!</SPAN></BODY></HTML> Thu, 03 Apr 2014 14:42:47 GMT https://community.esri.com/t5/arcobjects-sdk-questions/converting-cell-size-to-pixel-dimensions/m-p/129146#M3382 BradNace 2014-04-03T14:42:47Z
