This online calculator computes apparent temperature, taking into consideration wind speed and relative air humidity. It uses Australian Bureau of Meteorology formula
This online calculator finds the water boiling temperature given the atmospheric pressure in millimeters of mercury.
Clapeyron-Mendeleev equation. The relationship between the number of moles of gas, the temperature, volume and pressure.
Recalculation of density of oil for different temperature and pressure values. Formulas are taken from Russia's GOST R 8.610-2004. "State system for ensuring the uniformity of measurements. Density of oil. The tables for recalculation" standard
Calculator to determine conditions for drying grain.
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.
This calculator determines dew point from given temperature and relative humidity of air
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.
