In this case, in this particular context, the author has chosen (arbitrary) bounds and thus can use a <meter>: <p>Today's temperature in Dijon, France: <meter min=-20 max=40 value=21>21°C</meter></p> In this case, low="" and high="" could even be used to denote the minimum and maximum forecasted temperatures in the whole country (or region) and optimum="" could denote the average temperature for the same day-of-year over the last 10 years (in French, we call it "température normale de saison", I couldn't find the English equivalent) ...this only applies to the particular context of a particular weather forecast (other forecasts could use different bounds); you cannot use it for any temperature, like the temperature of your CPU ship (which would need other bounds) -- Thomas Broyer
