Google Maps picks miles or kilometers based on your region, but you can set the units yourself. The option is in the app settings on Android and iPhone, and in the directions options on a computer.
Quick Answer
In the Google Maps app, tap your profile picture, then Settings, then Distance units, and choose Kilometers or Miles. On a computer, get directions, click Options and pick km or miles.
How to Switch Google Maps From Miles to Kilometers
- Open the Google Maps app on your phone.
- Tap your profile picture or initial in the top-right corner.
- Tap Settings.
- Tap Distance units. On some versions it sits under Navigation settings.
- Choose Kilometers. Choose Automatic if you want the app to follow your region, or Miles to switch back.
- On a computer, search for a place, click Directions, then Options, and select km or miles. You can also click the scale bar in the corner of the map to flip its units.
Unit Settings by Device
| Where you use Maps | How to change units |
|---|---|
| Android app | Profile picture, Settings, Distance units |
| iPhone app | Profile picture, Settings, Distance units (or Navigation settings) |
| Computer browser | Directions, Options, km or miles |
| Map scale bar | Click it to switch between metric and imperial |
Troubleshooting
- If the setting does not seem to stick, check that you changed it in the app you actually use for navigation, and restart the app.
- Voice guidance follows the app setting, so it will announce kilometers once you switch.
- Speed limits and the speedometer usually follow the same unit choice, but local road signs still use the local unit.

Frequently Asked Questions
What does Automatic do?
It uses the unit that is standard where you are. In the US and UK that is usually miles; in most other countries it is kilometers.
Does changing units affect my other devices?
The app setting is saved per device, so change it on each phone or computer you use.
Can I show both miles and kilometers?
No. Google Maps shows one unit at a time, though the scale bar can show both on a computer.
Does walking and cycling use the same setting?
Yes. The unit applies to all travel modes. For walking routes, see how to change Google Maps to walking.
