The following letter was sent to the NWS via their feedback website: greg Has the National Weather Service ever considered adding Celsius temperature, kPa pressure, km/h wind-speed, and mm precipitation to your web site as a courtesy to international visitors and those Americans who prefer the metric system? I was under the impression that the US federal government used metric as the preferred system of measurement. I can obtain most of the US weather forecasts via the Environment Canada web site (all in metric, of course), but occasionally I prefer to obtain the information directly from the source. Having such units as �F, inHg, mph, and in makes it impossible to understand for anybody, except Americans. I am aware that Environment Canada has an "Imperial" option as a courtesy to American visitors. A reciprocated effort on your part would be greatly appreciated. Sincerely, Gregory Peterson Saskatoon SK Canada P.S> It is clear which system is easier to recall and why every country, except the US, has chosen to use metric for public weather: Freezing point 0�C 32�F Atmospheric pressure 101 kPa 29-13/16 inHg gentle wind 10 km/h 6 mph "hurricane" wind 100 km/h 60 mph typical rain fall 10 mm 3/8 in heavy rain fall 100 mm 4 in
