That’s true, but it’s also a double edged sword: you can easily learn metric just by switching to it.
Try setting a weather widget on your phone to only show you Celsius and don’t convert it to Fahrenheit, over time you will get an intuitive understanding of what feels cold to you.
The biggest block to learning a new system is insulating yourself with conversions IMO, imagine trying to learn a new language by just having everyone speak into Google translate
