I do this (inside a model what has latitude and longitude attributes)

RadConv=(Math::PI/180)

R=3958

def get_distance_to(to_lat, to_lon)

lat1=self.latitude * RadConv

lon1=self.longitude * RadConv

lat2=to_lat * RadConv

lon2=to_lon * RadConv

```
diff_lon = (lon2 - lon1).abs
diff_lat = (lat2 - lat1).abs
a = Math.sin(diff_lat/2) * Math.sin(diff_lat/2) + Math.cos(lat1) *
```

Math.cos(lat2) * Math.sin(diff_lon/2) * Math.sin(diff_lon/2);

c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));

d = R * c;

```
return d;
```

end

Thanks Andrew

but is there a way that i can do with geo code kit ?

any idea ?
