## rhumbDistance

Calculates the distance along a rhumb line between two [points][1] in [Units][2]

### Parameters

*   `from` **[Coord][3]** origin point
*   `to` **[Coord][3]** destination point
*   `options` **[Object][4]?** Optional parameters (optional, default `{}`)

    *   `options.units` **Units** Supports all valid Turf [Units][2] (optional, default `'kilometers'`)

### Examples

```javascript
var from = turf.point([-75.343, 39.984]);
var to = turf.point([-75.534, 39.123]);
var options = {units: 'miles'};

var distance = turf.rhumbDistance(from, to, options);

//addToMap
var addToMap = [from, to];
from.properties.distance = distance;
to.properties.distance = distance;
```

Returns **[number][5]** distance between the two points
