**Assembly:** CapyKit (in CapyKit.dll) Version: 1.0.2

**C#**
``` C#
public static double GetDistance(
	double latitudeOrigin,
	double longitudeOrigin,
	double latitudeDestination,
	double longitudeDestination,
	MeasurementSystem measurementSystem = MeasurementSystem.Imperial
)
```
**F#**
``` F#
static member GetDistance : 
        latitudeOrigin : float *
