When the weather is humid, the heat index indicates the human-perceived equivalent temperature
on the basis of air temperature and relative humidity (and other parameters)
The Humidex is a similar index by
based on air temperature and dewpoint temperature.
It is a dimensionless number. However, it indicates for humid air with which temperature
dry air would feel similarly.
Therefore, the values are given in degrees Celsius and degrees Fahrenheit.
Type the temperature and the relative humidity or the dew point temperature
into the corresponding fields.
After a mouse click on any free space of the window or the "calculate"-button
the calculation is performed.
Click on the "reset"-button to reset the calculation.
Move the mouse over a unit or click on it to read its full name.
For a calculation the air temperature must be higher than 26.6°C (80°F).
The valid range for relative humidity is 40 % to 100 %.
The dew point temperature must not be higher than the air temperature.
A temperature of 33°C and a relative humidity of 70 % have been measured.
Type the values into the corresponding fields.
After the next mouse click on any free space of the window or the
"calculate"-button you can read the result:
The heat index is 43°C and the humidex 47.4°C.
