Conversion to sea-level pressure Calculator

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)

    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.
