• Apparent temperature

    This online calculator computes apparent temperature, taking into consideration wind speed and relative air humidity. It uses Australian Bureau of Meteorology formula

  • Heat Index

    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.

  • Humidification loads

    This online calculator answers question "how to choose" humidifier, by calculating humidification requirements given initial and target relative humidity and building parameters

  • Humindex

    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.

  • Relative humidity to absolute humidity and vise versa calculators

    First calculator converts relative humidity to absolute humidity for given temperature and barometric pressure. Second calculator converts absolute humidity to relative humidity for given temperature and barometric pressure

  • Saturation vapour pressure

    This online calculator computes saturation vapour pressure for given temperature and atmospheric (barometric) pressure

  • Wind Chill Index

    This online calculator computes Wind Chill Index using Wind Chill Formula from Environment Canada
