# @turf/rhumb-distance

# rhumbDistance

Calculates the distance along a rhumb line between two [points](http://geojson.org/geojson-spec.html#point) in degrees, radians,
miles, or kilometers.

**Parameters**

-   `from` **([Geometry](http://geojson.org/geojson-spec.html#geometry) \| [Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)> | [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)<[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)>)** origin point
-   `to` **([Geometry](http://geojson.org/geojson-spec.html#geometry) \| [Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)> | [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)<[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)>)** destination point
-   `units` **\[[string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String)]** can be degrees, radians, miles, or kilometers (optional, default `kilometers`)

**Examples**

```javascript
var from = turf.point([-75.343, 39.984]);
var to = turf.point([-75.534, 39.123]);

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

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

Returns **[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** distance between the two points
