degToDirection()

degToDirection(integer  $degree) : string

Utility function to return textual cardinal compass directions from degress.

Parameters

Returns

The cardinal direction.

calculateWindChill()

calculateWindChill(double  $temperature, double  $speed) : double

Calculate windchill from temperature and windspeed.

Temperature has to be entered in deg F, speed in mph!

Parameters

Returns

The windchill factor.

calculateHumidity()

calculateHumidity(double  $temperature, double  $dewPoint) : double

Calculate humidity from temperature and dewpoint This is only an approximation, there is no exact formula, this one here is called Magnus-Formula

Temperature and dewpoint have to be entered in deg C!

Parameters

Returns

calculateDewPoint()

calculateDewPoint(double  $temperature, double  $humidity) : double

Calculate dewpoint from temperature and humidity This is only an approximation, there is no exact formula, this one here is called Magnus-Formula

Temperature has to be entered in deg C!

Parameters

Returns

convertPressure()

convertPressure(double  $pressure, string  $from, string  $to) : float

Convert pressure between in, hpa, mb, mm and atm

Parameters

Returns

The converted pressure

convertSpeed()

convertSpeed(double  $speed, string  $from, string  $to) : double|integer|boolean

Convert speed between mph, kph, kt, mps, fps and bft

Function will return 'false' when trying to convert from Beaufort, as it is a scale and not a true measurement

Parameters

Returns

convertDistance()

convertDistance(double  $distance, string  $from, string  $to) : double

Convert distance between m, km, ft and sm

Parameters

Returns

convertTemperature()

convertTemperature(double  $temperature, string  $from, string  $to) : double

Convert temperature between f and c

Parameters

Returns
