convertSpeed() публичный статический Метод

Function will return 'false' when trying to convert from Beaufort, as it is a scale and not a true measurement
public static convertSpeed ( double $speed, string $from, string $to ) : double | integer | boolean
$speed double The speed in $from units.
$from string The units to convert from.
$to string The units to convert to.
Результат double | integer | boolean
