corrected barometer* = 30.20 inHg
wind speed = 1.96 mph
wind direction* = NW (333°)
more info: current metric | historical | forecast | help
dew point = 60 deg f
saturation pressure = 0.538 inHg
vapor pressure = 0.527 inHg
grains = 79.9
air density (w/o water vapor) = 97%
air density (w water vapor) = 96%

This really important of you are using weather data for any correction input.

Ralph,
I am confused (that happens a lot these days). If the 29.71 BP Larry posted is corrected BP and you show corrected BP as 30.20. Why are they different?

I was thinking maybe corrected BP - Vapor Pressure but that does not workout.
