You can purchase a "Sea level altitude interpolater" from Ronco, and I heard if you do it in the next 15 minutes you get two Ginsu knives, free!!! :thumbs:Pugman1943 said:Now Tom, you bring up an interesting question. Sea level is relative to altitude. I'm here at 657 feet ASL, so what do I use to interpolate the difference from absolute sea level to my level above sea level?
