Note:
Heat Index:
The Heat Index is determined using the dry bulb temperature and relative
humidity.
It is based upon charts available from the U.S. National Weather Service.
The Heat Index represents how an average person feels relative to climate
conditions. For a given temperature, the higher the humidity, the higher the heat
index will be.
The Heat Index is defined over a temperature range of 70°F to 120°F (21°C to
49°C) and a relative humidity range of 30% to 99%. Outside of this range, the
meter will show dashes in the display for the Heat Index.
Humidex :
The Humidex, use primarily in Canada, works on the same concept as the
Heat Index. The values are slightly different. The Humidex is defined over a
temperature range of 70°F to 109°F (21°C to 43°C) and a relative humidity range
of 20% to 99%. Outside of this range, the meter will show dashes in the display
for the Humidex.
Wind Chill Temperature:
The Wind chill temperature (Twc), use by the U.S. and Canadian weather services,
which is determined by iterating a model of skin temperature under various wind
speeds and temperatures.
The Wind chill temperature is defined over a temperature range of -58°F to +41°F
(-50°C to +5°C) and a wind speed above 176 ft/m (0.9m/s). Outside of this range,
the meter will show dashes in the display for the Wind chill temperature.
