FYI, In France, we also use SI units, hPa for atmospheric pressure, but m/s in technical reports (marine, aviation. ..) and km/h in "consumer" products aka weather forecasts on TV... HTH Best regards,

Also air pressure >(millibars/hectopascals/pascals/?). Whatever you do, use SI units internally and make it an option for the user to get those. Convert from SI to whatever the user wants in their local cultural geograpy. PS: In Denmark we use the SI units: Meter per second and hectopascal.
