Calculates the sea-level pressure from the atmospheric pressure, temperature and altitude at the present location.

The atmospheric pressure shown on the weather map is adjusted to the equivalent sea level pressure. (1atm=1013.25hPa)

    Purpose of use
    To aid in properly calibrating electronic and aneroid pressure measurement devices.
    Comment/Request
    An option for data entry in metric or English units would be "convenient," but not very "scientific" eh? Oh well, never mind, this works very nicely and helped me trim a device into reality.

    Purpose of use
    Ultimately to see the mass of a CoCoRaHS rain gauge when cold vs. warm - i.e. how much extra weight does cold air in the gauge bring? I think it's measurable with inexpensive scales!
