We are about 600 feet above sea level. How much should I subtract from the sea level pressure to arrive at the barometric pressure at my location? What is the standard per foot?
Standard sea level pressure is expressed as 29.92 inches of mercury. In the lower few thousand feet of the troposphere — the “air” surrounding earth that we live in — pressure decreases roughly one inch for each 1,000 feet increase in altitude. Thus, the standard, uncorrected pressure at your home 600 feet above sea level would be 29.32 inches of mercury.
