### 2/5 — Could be useful, in North America

*2023-10-23*

For a European manufacturer, it's odd that this App only allows you to use gallons, Fahrenheit, and PSI.  As such, it's of limited use to Europeans used to working with litres, Celsius, and Bars - which is what most Zilmet EVs have on their labels...

Surely it would take very little effort to allow users to define their default formats?  If so, then this would be one of the better Apps for EV sizing.
