When using the Activity app on Apple Watch you may find yourself frustrated with its assumption that you want to know your distance in kilometers (km) instead of miles. Or vice versa. Can you switch the Apple Watch from km to miles? Yes, you can, but it’s not immediately obvious how to do it.

We’re going to show you how with a step-by-step guide.

Time needed: 2 minutes.

How to switch Apple Watch Activity distances from km to miles

Open up the Health app on your iPhone
Rather than this being managed by the Activity app, it’s actually done via Health
Head to the Walking & Running Distance screen
Click on the “Browse” tab at the bottom, then select “Activity” and then the “Walking & Running Distance” card
Find the options
Scroll to the bottom of this screen, where there is a section named “Options”.
Change the units
At the bottom is one named “Unit”. Click on this, and change from “km” to “mi”.
Check Activity
Head into the Activity app information and you should now find your distances show as miles.
