How to change units on Apple Watch

Choose Metric or Imperial measurements for LilyMaps on your Apple Watch.

Choose the measurements you know

Metric (Kilometers) uses meters and kilometers. Imperial (Miles) uses feet and miles. Choose the one you are used to; LilyMaps changes the labels, not your maps, routes, or recordings.
