title: Change banner instruction from miles to meter or km
body: <p><strong>Change distance display in banner instruction from mi or feet to km or meter</strong></p>
  
  <p>I am following instruction in
  <a href="https://docs.mapbox.com/help/tutorials/android-navigation-sdk/" rel="nofollow noreferrer">https://docs.mapbox.com/help/tutorials/android-navigation-sdk/</a></p>
  
  <p>as i have my specific route, I try to develop a routing server as part of my own project, I am able to feed the routing json into directionsresponse object. The distance it self in banner instruction shows miles, while i am using meter as distance. I can change the distance in miles easily but that is not what i want to achieve.</p>
  
  <p>Sorry, i havent try any code to change it as i have no idea where to start.</p>
  
  <p>expected result will me like </p>
  
  <pre><code>150 meters
  </code></pre>
  
  <p>while now i have </p>
  
  <pre><code>150 mi
  </code></pre>
  
  <p>I understand that there is a question that similar, but the only answer is will be developed , and that was in 2017.</p>
  
  <p>and i am not sure why people give -1 to this question.</p>
  
  <p>I plan to release this project in the next 3 month in the github as a guide for beginner like me to develop a python base routing server.</p>
  
  <p>Cheers</p>
