We support both the Metric and the Imperial system.
You can set the Metric or Imperial system in the applications themselves. You can also set the preference in the Selfloops website. For the website, follow this link: https://www.selfloops.com/account/profile
In the Metric system: Kilograms KG are used for the weight, Km and Km/hour are used for distance and speed.
