Absolute and relative pressure

  • There is no correction for atmospheric pressure relative to sea level. The absolute units in which the pressure is displayed now have to be counted by hand ?? For every 100 meters of altitude, as far as I remember (I may be mistaken), this is a coefficient of 0.00859352154522145. So, the absolute atmospheric pressure in my city is 755 mmHg, and the relative (at an altitude of 200m) is 737.5 mmHg

    The free Current Weather Data and One Call API 1.0 do not provide the altitude or the ground level pressure. The free 5 Day / 3 Hour Forecast provides the altitude and the pressure at sea and ground level. Unfortunately, it returns only 5 days (instead of 7) and the hourly forecast is in 3-hour increments.
    I’ll have to combine the altitude from the 5 Day / 3 Hour call with the sea level pressures from the other 2 calls to calculate the ground level pressure.

    Would you want to see both pressures or rather have a check box where you can select ground or sea level?
