 | `precision` | `String` | `"low"` | The precision level of detail of the drawn polyline. Allowed values are "high", and "low". Setting to "low" will yield a polyline that is an approximate (smoothed) path of the resulting directions. Setting to "high" may cause a hit in performance in case a complex route is returned.
 | `timePrecision` | `String` | `"none"` | The timePrecision to get Realtime traffic info. Allowed values are "none", and "now". Defaults to "none".
 | `channel` | `String` | `null` | If you include the channel parameter in your requests, you can generate a Successful Requests report that shows a breakdown of your application's API requests across different applications that use the same client ID (such as externally facing access vs. internally facing access).
+| `unitSystem` | `String` | `metric` | Specifies the unit system to use when displaying results. Directions results contain text within distance fields that may be displayed to the user to indicate the distance of a particular "step" of the route. By default, this text uses the unit system of the origin's country or region. For example, a route from "Chicago, IL" to "Toronto, ONT" will display results in miles, while the reverse route will display results in kilometers. You may override this unit system by setting one explicitly within the request's units parameter, passing one of the following values: `metric` specifies usage of the metric system. Textual distances are returned using kilometers and meters. `imperial` specifies usage of the Imperial (English) system. Textual distances are returned using miles and feet.  ).
 #### More props
 
 Since the result rendered on screen is a `MapView.Polyline` component, all [`MapView.Polyline` props](https://github.com/airbnb/react-native-maps/blob/master/docs/polyline.md#props) – except for `coordinates` – are also accepted.
