To change the sizing units for your talent, for example, to switch from metric to imperial units, you can do so directly within your account. This is helpful if your location may be in one location, but a majority, or all, of your talent are in another, for example, in the United States.
After logging into your account, navigate to your settings and select Language & Region. At the bottom of that page, you can choose between Metric or Imperial:
Once you've made your selection, make sure you hit Save.
Please note: this will apply to all talent in your account. Currently, there is not a way to change this setting for a single talent.
