|Wind Chill Index|
This online calculator computes Wind Chill Index using Wind Chill Formula from Environment Canada
This online calculator computes the apparent temperature, taking into consideration wind speed and relative air humidity. It uses the Australian Bureau of Meteorology formula
|Saturation vapor pressure|
This online calculator computes saturation vapor pressure for a given temperature and atmospheric (barometric) pressure
|Relative humidity to absolute humidity and vice versa calculators|
The first calculator converts relative humidity to absolute humidity for a given temperature and barometric pressure. The second calculator does the opposite - converts absolute humidity to relative humidity for a given temperature and barometric pressure. Some theory and formulas can be found below the calculator.
|Humidification load calculator|
This online calculator answers question "how to choose" humidifier, by calculating humidification requirements given initial and target relative humidity and building parameters
This calculator calculates Humindex, index used by Canadian meteorologists to describe how hot the weather feels to the average person, by combining the effect of heat and humidity.
This calculator calculates heat index (apparent temperature), which is used by US meteorologists to determine the human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade.
