- Altitude Pressure
This calculator uses barometric formula to find out the pressure at the given altitude

- Angular velocity and linear velocity
This online calculator converts angular velocity to linear velocity for given radius

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

- Area de la Sombra de un Objeto
El área de la sombra se refiere a la de un objeto cuadrado o rectangular.

- Barometric leveling

Acceleration of gravity calculation on the surface of a planet. It's possible to calculate the acceleration above the surface by setting the sea level. But it won't be possible under thesurface - this is a wrong formula.

- Battery discharge time depending on load
This article contains online calculators which can calculate discharge times for specified discharge current using battery capacity, the capacity rating (i.e. 20 hour rating, 100 hour rating etc) and Peukert's exponent.
