Make altitude and precipitation units separate

Hi! I’d like to suggest adding separate unit settings for altitude and precipitation. In aviation contexts (especially in Europe) altitude is commonly measured in feet, while precipitation is typically shown in millimeters. Right now, the app ties both to the same unit system, so I have to choose between feet with inches or meters with millimeters. It would be much more useful if altitude and precipitation units could be selected independently. Thanks for considering this improvement!
