I find over and over again that weather applications and web sites default to temperatures in °F and wind speeds in mph. My local standard (which is "local" in most of the world, I believe) is °C and m/s. Is there any standard for specifying this? The regular locale settings do not seem to have a slot for this.
(Some American weather sites "helpfully" convert mph to km/h but that's pretty useless. A codified standard would help them do the right thing, too.)
